#INTELLIJ JAR RED CODE#

You can use this console to try out code snippets, and you will be able to select the module path for running this code. In addition, IntelliJ IDEA 2017.3 also has a basic console that allows you to work with JShell from inside the IDE, similar to the Groovy Console. You can run this REPL from the command line, or from the terminal inside IntelliJ IDEA. Java 9 comes with a REPL for Java for the first time, called JShell. If youРІР‚в„ўve got this inspection turned on and set to РІР‚СљWarningРІР‚Сњ (which is the default), then when youРІР‚в„ўreР’В using something thatРІР‚в„ўs been tagged as РІР‚СљforRemovalРІР‚Сњ, IntelliJ IDEA will strike this method through in red, rather than the usual black. ThereРІР‚в„ўs a new inspection in IntelliJ IDEA 2017.3 that highlightsР’В any use of code that has been marked РІР‚СљforRemovalРІР‚Сњ. Now instead of merely tagging code as deprecated and (possibly) documenting the reasons in the Javadoc,Р’В the tag supports two useful new attributes, РІР‚СљsinceРІР‚Сњ and РІР‚СљforRemovalРІР‚Сњ. This inspection and the one for Convenience Factory Methods were covered previously in the blog post and video on Java 9 support in IntelliJ IDEA 2017.2.Р”Р„nother seemingly small feature in Java 9Р’В that makes it easier for developers to understand the impact of their code is enhanced deprecation. IntelliJ IDEA locates code where this hint may be useful, and can add it. Specifically, if your code is spinning in a loop waiting for something to happen, you can use Thread.onSpinWait to let the runtime know. Java 9Р’В lets you give hints to the JVMР’В that can helpР’В performance. This will highlight code that can be simplified by using the Java 9 factory methods IntelliJ IDEA 2017.2 introduced an inspection which can show you where you can use this feature. One of these is to simplify the creation of Collections with fixed contents. Java 9 introduces a lot of small API changes that made life easier for developers. This is important as these automatic modules may change over time.Р”Р‡ind out more about basic support for modules in IntelliJ IDEA, and module diagrams and additional quick fixes. This means you can see if youРІР‚в„ўre dependent on something that isnРІР‚в„ўt a true Java 9 module. For example, you canР’В highlight the use of automatic modules. IntelliJ IDEA has inspectionsР’В to help migrate code to Java 9. You can even navigate to the modules from the diagram.

These diagrams are particularly useful when youРІР‚в„ўre getting started with modularity, as they help you understand which modules youРІР‚в„ўre using and where they come from. You can see JDK modules, yourР’В own modules and automatic modules in different colours, and transitive requirements are highlighted with a stronger line. IntelliJ IDEA also lets you create module diagrams to help you visualise the modules youРІР‚в„ўre using.

Or detection ofР’В duplicate directives or other errors that can be fixed IntelliJ IDEA also offersР’В quick fixes for some of the common problems youРІР‚в„ўll face as you migrate your code to the JPMS, such as the ability to add a РІР‚СљrequiresРІР‚Сњ directive If you runР’В code from a module with a module-info.java file, IntelliJ IDEA will automatically use the -p argument (module path) instead of -classpath. While youРІР‚в„ўre working in this file you get codeР’В highlighting and completion of course. This will give you the basic structure of your moduleР’В declaration, including a module name that matches the name of your IntelliJ IDEA module. You can easily create a module-info.java file for your IntelliJ IDEA modules: IntelliJ IDEA has supported the Java Platform Module System sinceР’В 2016.3,Р’В this support was added to and improved in 2017.1.

Jigsaw itself is a much bigger undertaking and includes things like the modularisation of the JDK itself, whatРІР‚в„ўs interesting to us as developers is the JPMS. The big feature for Java 9 is, of course, the Java Platform Module SystemР’В (JPMS), which comes under the umbrella Project Jigsaw.

Java 9 has beenР’В fully supported in all of the 2017 releases,Р’В and most of the features we talk about here are available inР’В the current stable release of IntelliJ IDEA. Java 9 is released today, so letРІР‚в„ўsР’В do a quick recap of the existing Java 9 support in IntelliJ IDEA, and have a peek at some of the upcoming features in IntelliJ IDEA 2017.3 for Java 9.
