Unfortunately, this library is implemented only in Python so you can't really use it as is as part of your application. Jep will help you solve that exact problem.On a side note, there are other libraries that will help you achieve the same goal like jpy and jython for example, but they are less popular or not as actively maintained as Jep is.Set up your environmentJDK - Jep uses JNI in order to execute Python code, so running your application with JRE will not suffice since it doesn't include the required JNI module.Python - both Python 2.x and 3.x is supportedInstall Jep Python library, simply run:Install Jep Java library. In case you are using gradle, for example, add the following dependency to your build.gradle:implementation group: 'black.ninia', name: 'jep', version: '3.9.1'Finally, you'll need to inject your Java application with a new JVM argument pointing to your Jep Python library installation directory, for example:-Djava.library.path=/Users//Library/Python/3.9/lib/python/site-packages/jepGetting startedNow that everything is setup, we will show you how to work with Jep.First we'll need to create a new SharedInterpreter instance which we will use throughout our Java code.Then, using that interpreter, we will:Inject a String argument which will be used by the Python code:Our Python script argument named user_name will get the value of our Java code name variable.Execute the Python code using exec() methodGet a return value from Python back to JavaThat's it. It's as simple as that.Now you can install any Python library you need, import it in your Python code and then execute it as part of your Java code.Running a scriptThe more common use case for Jep is running an entire Python script with a single Java command. This way you don't need to call the exec() method over and over again for each Python code line you have.This approach is very useful in case you have an existing Python code which you want executed as part of your Java application.Type conversionEvery Java type being sent to Python using the interpreter is being converted to its counterpart. This applies to

JEP Package Tool in Java - GeeksforGeeks

On September 20, 2022, the most recent version of Java 19, or JDK 19, was published. It includes 7 significant platform advancements that should make developers’ jobs easier.In this blog, we will go through the major benefits of Java 19 and how it can help you in the long run for top-notch Java development.A Quick Glance on Java 19Structured ConcurrencyVirtual ThreadsA Preview of record patternForeign Function & Memory API (Preview)Pattern Matching for switchVector APIPort the JDK to Linux/RISC-V (2 incubators and 4 preview features,1 final feature under Hotspot Compiler)Structured Concurrency (preview)JEP 428 has two objectives –Improve the multithreaded code’s ability to be dependable, observable, and maintainable.Promote the use of concurrent programming methods that can lessen common shutdown and cancellation risks, such as thread leaks and cancellation delays.In Project Loom, Structured Concurrency is also included. By treating many jobs running in distinct threads as a single unit of work, it seeks to make Java concurrent programming simpler. A method provided by JEP 428 enables the division of a task into multiple concurrent subtasks that all end up in the same code block.Multithreaded programming can be simplified by structured concurrency, a phase of development in which a structured concurrency API is being developed. To streamline error handling and cancellation, multiple tasks are treated as a single unit of work. The lightweight concurrency model introduced in Project Loom improves reliability and observability.Virtual ThreadsDue to their lightweight operation, virtual threads are useful for high-throughput concurrent applications. This preview API will not only allow thread-per-request style applications to scale efficiently, but it will also make it easier to incorporate this API seamlessly into Java.Additionally, it will make it possible to monitor, debug, and diagnose virtual threads using already-existing JDK tools without changing the fundamental concurrency paradigm for Java or getting rid of the traditional thread execution.A Preview of record patternA sneak peek at record patterns to break down record values. It is possible to nest record forms and type patterns to provide declarative, potent, and modular data processing. The proposal aims to enhance pattern matching to describe more complex, composable data searches without altering type patterns’ syntax or semantics. The pattern matching for instance of the feature introduced in JDK 16 in March 2021 serves as the foundation for this proposal. Record patterns may eventually get access to capabilities like array patterns and vararg patterns. Project Amber, which aims to investigate and develop more compact, Java features that are focused on productivity, includes Record Patterns.Foreign Function & Memory API (Preview)Java developers have a few options available when it comes to obtaining off-heap data: Should they choose the safe but inefficient route (ByteBuffer) or should they choose performance above safety (Unsafe)?A new API in Java 19 enables Java programs to communicate with code and information not included in the Java runtime. The API efficiently executes foreign functions (i.e., code outside the JVM) and securely accesses foreign memory, allowing Java programs to call native libraries and manage native data without the fragility and risk of JNI.Consider a.

For more details see method asMatchPredicate(): Predicate.3) Other Features of Interest to Developers3.1) Profiling JVM Apps – Addition of Flight RecorderFlight Recorder is an existing low-overhead profiling tool (set of APIs etc) designed and built by Oracle engineers to support troubleshooting, monitoring and profiling the JVM and apps, whilst running in production, with minimal overhead. Prior to JDK 11, the tool was only available as a paid feature in the Oracle JDK. In JDK 11, Oracle have contributed Flight Recorder to the open source OpenJDK project, as part of their ongoing process to migrate the Oracle JDK to use/share the OpenJDK project source code, and remove any proprietary features. As a result, Flight Recorder is now free to use in JDK 11. The relevant APIs and Java classes are packaged in two new JDK modules – jdk.jfr and jdk.management.jfr. For more details see JEP 328: Flight Recorder.3.2) Security – TLS 1.3 SupportThe Java Secure Socket Extension (JSSE) in the JDK provides a Java implementation of the SSL, TLS, and DTLS protocols. Prior to JDK 11, the JSSE API and JDK implementation supported SSL 3.0, TLS 1.0, TLS 1.1, TLS 1.2, DTLS 1.0 and DTLS 1.2.TLS 1.3 (RFC 8446) is a new, major overhaul of the TLS protocol which supersedes, obsoletes and provides significant security and performance improvements over TLS 1.2. Several early implementations from other vendors have already become available, and are starting to be used. JDK 11 has been enhanced to support the essential parts of TLS 1.3, in order to remain a competitive/relevant stack from a web security perspective and ensure continued compatibility, although this does not yet extend to Datagram Transport Layer Security (DTLS).For more details see OpenJDK JEP addition to the above, as is usual, this major new release of the JDK also includes hundreds of smaller enhancements and countless bug fixes, as well as performance improvements.4) Upgrade ConsiderationsWhen planning your upgrade to JDK 11, consider the following issues.4.1) Third Party Software

Jep – Embedding Python in Java - fxis.ai

一、JAVA12概述 2019年3月19日,java12正式发布了,总共有8个新的JEP(JDK Enhancement Proposals) JDK 12 is the open-source reference implementation of version 12 of the Java SE12 Platform as specified by by JSR 386 in the Java Community Process. JDK 12 reached General Availability on 19 March 2019. Production-ready binaries under the GPL are available from Oracle; binaries from other vendors will follow shortly. The features and schedule of this release were proposed and tracked via the JEP Process, as amended by the JEP 2.0 proposal. The release was produced using the JDK Release Process(JEP 3). JAVA12的版本特性地址： Low-Pause-Time Garbage Collector(Experimental) 低暂停时间的GC 230:Microbenchmark Suite 微基准测试套件 325:Switch Expressions(Preview) switch表达式 334:JVM Constants API JVM常量API 340:One AArch64 Port,Not Two 只保留一个AArch64实现 341:Default CDS Archives 默认类数据共享归档文件 344:Abortable Mixed Collections for G1 可中止的G1 Mixed GC 346:Promptly Return Unused Committed Memory from G1 G1及时返回未使用的已分配内存 switch 表达式(预览) 传统的switch声明语句(switch statement)在使用中有一些问题：匹配自上而下,若无break, 后面的case语句都会执行；不同的case语句定义的变量名不能重复；不能在一个case里写多个执行结果一致的条件；整个switch不能作为表达式返回值；Java 12提供增强版的 switch 语句或称为 "switch 表达式"来写出更加简化的代码。什么是预览? Switch 表达式也是作为预览语言功能的第一个语言改动被引入新版 Java 中来的，这是一种引入新特性的测试版的方法。通过这种方式，能够根据用户反馈进行升级、更改.如果没有被很好的接纳，则可以完全删除该功能。预览功能的没有被包含在Java SE 规范中。也就时说: 这不是一个正式的语法,是暂时进行测试的一种语法.switch详细语法 扩展的 switch 语句，不仅可以作为语句（statement），还可以作为表达式（expression），并且两种写法都可以,使用传统的 switch 语法，或者使用简化的“case L ->”模式匹配语法作用于不同范围并控制执行流。这些更改将简化日常编码工作，并为 switch 中的模式匹配（JEP 305）做好准备。使用 Java 12 中 switch 表达式的写法，省去了 break 语句，避免了因少写 break 而出错。同时将多个 case 合并到一行，显得简洁、清晰也更加优雅的表达逻辑分支，其具体写法就是将之前的 case 语句表成了：case L ->，即如果条件匹配 case ，则执行标签右侧的代码 ，同时标签右侧的代码段只能是表达式、代码块或 throw 语句。为了保持兼容性，case 条件语句中依然可以使用字符 : ，这时 fall-through 规则依然有效的，即不能省略原有的 break 语句，但是同一个 switch 结构里不能混用 -> 和 : ，否则会有编译错误。并且简化后的 switch 代码块中定义的局部变量，其作用域就限制在代码块中，而不是蔓延到整个 Switch 结构，也不用根据不同的判断条件来给变量赋值。JAVA12之前switch语法的使用： public static void main(String[] args) { Month month=Month.APRIL; String season; switch (month){ case DECEMBER: case JANUARY: case FEBRUARY: season="冬"; break; case MARCH: case APRIL: case MAY: season="春"; break; case JUNE: case JULY: case AUGUST: season="夏"; break; case SEPTEMBER: case OCTOBER: case NOVEMBER: season="秋"; break; default: throw new RuntimeException("NoSuchMonthException"); } System.out.println(season); }JAVA12之后，switch语法的用法: public static void main(String[] args) { Month month=Month.APRIL; String season; switch (month){ case DECEMBER,JANUARY,FEBRUARY ->season="冬"; case MARCH,APRIL,MAY -> season="春"; case JUNE,JULY,AUGUST -> season="夏"; case SEPTEMBER,OCTOBER,NOVEMBER -> season="秋"; default -> throw new RuntimeException("无效数据"); } System.out.println(season); } 似乎可以看出,JAVA开发者或将逐渐的从复杂繁琐的底层抽象代码的编写中解放出来,编写一些更高层次更优雅的代码. 减少出错,提高开发效率. 目前switch表达式支持下面的数据类型, byte char short int Byte, Character,Short,Integer,enum,String,未来是否会支持 float double和long? 目前本版本未对支持的数据类型进行拓展.三、API层次的改变1.支持数字压缩格式化 NumberFormat 添加了对以紧凑形式格式化数字的支持。紧凑数字格式是指以简短或人类可读形式表示的数字。例如，在en_US语言环境中，1000可以格式化为“1K”，1000000可以格式化为“1M”，具体取决于指定的样式NumberFormat.Style。var cnf = NumberFormat.getCompactNumberInstance(Locale.CHINA,NumberFormat.Style.SHORT);System.out.println(cnf.format(1_0000));System.out.println(cnf.format(1_9200));System.out.println(cnf.format(1_000_000));System.out.println(cnf.format(1L 2. String新方法String#transform(Function) : 它提供的函数作为输入提供给特定的String实例，并返回该函数返回的输出。 public static void main(String[] args) { var result = "波波".transform(input -> input + "烤鸭"); System.out.println(result); //波波烤鸭 result = "bobo" .transform(input -> input + " kaoya") .transform(String::toUpperCase); System.out.println(result); }输出结果：transform源码分析： /** * This method allows the application of a function to {@code this} * string. The function should expect a single String argument * and produce an {@code R} result. * * Any exception thrown by {@code f.apply()} will be propagated to the * caller. * * @param f a function to apply * * @param the type of the result * * @return the result of applying the function to this string * * @see java.util.function.Function * * @since 12 */ public R transform(Function f) { return f.apply(this); } 传入一个函数式接口 Function，接受一个值，返回一个值，连续调用transform方法,对字符串进行连续三次的改变. public static void main(String[] args) { List list1 = List.of("Java", " Golang", " Python "); List list2 = new ArrayList(); list1.forEach(element -> list2.add(element.transform(String::strip) .transform(String::toUpperCase) .transform((e) -> "Hello," + e)) ); list2.forEach(System.out::println); }结果为:

Do you hit a brick wall and cannot chat or play games? Well your answer is Java Embedding Plugin. I have been using this since I found it on MacUpdate and it is great to not have to switch to Safari in order to play games or chat. It works...it really, really works. Give it a try.From MacUpdate: Quote: Java Embedding Plugin 0.9.2: The Java Embedding Plugin is a utility (currently in beta release) that allows other web browsers than Apple's Safari to use the most recent versions of Java (1.4.X) on Mac OS X. Currently it supports recent versions of the Mozilla "family" of browsers, when used together with an updated version of Mozilla's MRJ Plugin Carbon (included in this distribution). But in principle any web browser could use one of the Java Embedding Plugin's two APIs to add support for Java 1.4.X.The current versions of the Java Embedding Plugin and the updated MRJ Plugin Carbon have been tested with Mozilla 1.6 and 1.7.X, Firefox 0.8 and 0.9.X, and Camino 0.7 and 0.8.X on OS X 10.2.8 with Java 1.4.1 and OS X 10.3.5 with Java 1.4.2 Update 1 and Java 1.4.2 Update 2.The current version (0.8.6) of the Java Embedding Plugin has not been tested with Java 1.4.2 "plain" or on Mac OS X 10.3.3 or 10.3.4. But previous versions of the JEP (e.g. 0.8.2) worked in these environments, and so (I believe) should version 0.8.6.Apple's Java 1.4.2 and above have one additional requirement, unrelated to the Java Embedding Plugin -- an appropriate version of the JavaPluginCocoa.bundle must be present in the /Library/Internet Plug-Ins folder.What's New:Version 0.9.2: * Fixed a major security hole in the MRJ Plugin that effects all nightlies, alphas and betas of Mozilla-family browsers issued since 2004-04-25, but none of the "released" versions. So, for example, Firefox 1.0.X,.

nathanfunk/jep-java-gpl: Java Math Expression Parser

Process. Before you could run a program using the ‘java’ command you first needed to compile it using ‘javac’. Java 11 streamlines the process by allowing you to launch (both compile and run) a Java program implemented in a single source file using the ‘java’ command alone.For example, given a Java source file ~/src/test/java/com/neiljbrown/java11/HelloWorld.java containing the following code –package com.neiljbrown.java11;public class HelloWorld { public static void main(String[] args) { String greeting = "Hello " + (args.length > 0 ? args[0] : "World!"); System.out.println(greeting); }}Using a Java 11 JDK you can launch (compile and run) the program using the following single command –$ java -classpath ~/src/test/java com/neiljbrown/java11/HelloWorld.java Duke!!resulting in the following outputHello Duke!!This feature is mostly designed to make Java easier to learn for beginners (in a similar way to JShell), but it also reduces the ceremony for running simple utility programs written in Java, making it closer to running a script. In this regard, there is also support for executing Java source code from a script using the ‘shebang’ support provided by *nix O/S. For example –$ cat > hello-world.sh#!/Users/neilbrown/.sdkman/candidates/java/11.0.2-open/bin/java --source 11public class HelloWorld { public static void main(String[] args) { String greeting = "Hello " + (args.length > 0 ? args[0] : "World!"); System.out.println(greeting); }}$ chmod +x hello-world.sh$ ./hello-world.sh Duke(Note, when using shebang support as above, the file can have any extension, including none, except “.java”). For more details of the feature see JEP 330: Launch Single-File Source-Code Programs.2.4) Enhancements to the Standard Library APIsA few minor enhancements have been made to the Java SE library APIs in JDK 11. Those that will be of most use in everyday development are outlined below.2.4.1) java.lang.StringThe java.lang.String API has been extended to add several useful methods for performing commonly required operations on strings, which will reduce (although is still a long way from eliminating) the need to use thirdparty library support. The new methods include, e.g.isBlank() : boolean – Checks whether the string is blank – is empty (as indicated by existing isEmpty() method) or also contains only whitespace characters.strip() : String – Removes leading and trailing whitespace from the string.
