Feb 05,  · Java Java Programming Java 8 Let us look at an example that creates a package called animals. It is a good practice to use names of packages with lower case letters to avoid any conflicts with the names of classes and interfaces. May 23,  · While many programming environments allow us to compile and run a program within the environment, we can also compile and run java programs using Command Prompt. After successful installation of JDK in our system and set the path, we can able to compile and execute Java programs using the command prompt. Make sure that you are inside the parent directory of the package folder (the folder in which your compiled class file is), and execute the following command: java solarigniters.coms Below is an example file structure: bin -> myclass ->

In this tutorial, you will learn how to create, run, and package a simple Java application that prints Hello, World! Along the way, you will get familiar with IntelliJ IDEA features for boosting your productivity as a developer: coding assistance and supplementary tools.

In IntelliJ IDEA, a project helps you organize your source code, tests, libraries that you use, build instructions, and your personal settings in a single unit. If the Welcome screen opens, click New Project. Otherwise, from the main menu, select File New Project. In the New Project wizard, select Java from the list on the left.

We're not going to use any additional libraries or frameworks for this tutorial, so click Next. Don't create a project from the template. In this tutorial, we're going to do everything from scratch, so click Next. If necessary, change the default project location and click Finish. Packages are used for grouping together classes that belong to the same category or provide similar functionality, for structuring and organizing large applications with hundreds of classes.

In the Name field, type com. HelloWorld and click OK. In this case, the IDE has inserted the package statement and the class declaration. This is done by means of file templates. Depending on the type of the file that you create, the IDE inserts initial code and formatting that is expected to be in all files of that type. For more information on how to use and configure templates, refer to File templates. Type main and select the template that inserts the main method declaration.

Live templates are code snippets that you can insert into your code. Usually, live templates contain blocks of code that you use most often. Using them can save you some time as you don't have to type the same code over and over again. For more information on where to find predefined live templates and how to create your own, refer to Live templates. Let's call a method that prints some text to the standard system output. Type Sy and select the System class from the list of code completion suggestions it's from the standard java.

Type p , select the println String x method, and press Enter. This information is for your reference. Type ". The second quotation mark is inserted automatically, and the caret is placed between the quotation marks.

Type Hello, World! Basic code completion analyses the context around the current caret position and and provides suggestions as you type.

For information on different completion modes, refer to Code completion. Valid Java classes can be compiled into bytecode. You can compile and run classes with the main method right from the editor using the green arrow icon in the gutter. Click in the gutter and select Run 'HelloWorld.

The IDE starts compiling your code. When the compilation is complete, the Run tool window opens at the bottom of the screen.

The second line shows the program output: Hello, World! And the last line shows the exit code 0 , which indicates that it exited successfully. If your code is not correct, and the IDE can't compile it, the Run tool window will display the corresponding exit code. First, it builds your application.

On this stage, javac compiles your source code into JVM bytecode. Once javac finishes compilation, it places the compiled bytecode to the out directory, which is highlighted with yellow in the Project tool window. After that, the JVM runs the bytecode.

IntelliJ IDEA automatically analyzes the file that is currently opened in the editor and searches for different types of problems: from syntax errors to typos.

The Inspections widget at the top-right corner of the editor allows you to quickly see all the detected problems and look at each problem in detail. For more information, refer to Current file. When the code is ready, you can package your application in a Java archive JAR so that you can share it with other developers. A built Java archive is called an artifact. Click , point to JAR and select From modules with dependencies. To the right of the Main Class field, click and select HelloWorld com.

From the main menu, select Build Build Artifacts. Point to HelloWorld:jar and select Build. Name the new configuration: HelloWorldJar. Doing this means that the HelloWorld. Run configurations allow you to define how you want to run your application, with which arguments and options. You can have multiple run configurations for the same application, each with its own settings.

On the toolbar, select the HelloWorldJar configuration and click to the right of the run configuration selector. As before, the Run tool window opens and shows you the application output.

The process has exited successfully, which means that the application is packaged correctly. Create your first Java application In this tutorial, you will learn how to create, run, and package a simple Java application that prints Hello, World!
