Utilize Java SDK or an online compiler to validate your Java programs
This Mytour demonstrates the process of transforming your Java source code into an executable application using either a local compiler or an online compiler. For desktop users, the conventional approach involves utilizing the Java Software Development Kit (Java SDK) through the command line. Conversely, for mobile users or those without access to a compiler-equipped system, platforms like Codiva offer a convenient online compilation service.
Essential Information
- If you have the Java SDK installed, navigate to your computer's command prompt to compile your Java program.
- An online compiler provides a hassle-free and lightweight alternative to ensure the correctness of your code.
- Online compilers often feature autosave functionality, mitigating the risk of data loss in case of unexpected events.
Procedure
Utilizing Java Software Development Kit
Access the command prompt. You can leverage the Java Software Development Kit (Java SDK) via the command prompt on Windows, macOS, or Linux. If the Java SDK isn't installed, refer to How to Install the Java Software Development Kit. Below are the steps to access the command prompt on each platform:
- Windows: Right-click the Start menu and choose Command Prompt. If you don't find this option, enter cmd in the Windows Search bar and select Command Prompt from the results.
- macOS: Click the magnifying glass at the top-right corner of the screen to open Spotlight, type terminal, and then click Terminal in the search outcomes.
- Linux: Press Ctrl+Alt+T.
Navigate using the cd command to the directory containing your Java code. The Java source code file ends with the .java file extension.
Enter javac sourcecode.java and press ↵ Enter or ⏎ Return. Substitute sourcecode.java with your source file's name. This action compiles your source code into an executable file with the .class extension.
- To view the newly created file's name in the current directory, execute the dir (Windows) or ls -a (Mac/Linux) command.
- If you encounter an error while attempting to do so
Type java programname and hit ↵ Enter or ⏎ Return. Replace programname with your program's name. This will execute the program via the command line.
Utilizing an Online Java Compiler
Visit https://www.codiva.io using a web browser. Codiva serves as an online Java compiler, particularly beneficial for individuals without access to a local compiler, even on mobile devices.
Log in or register for an account. For newcomers to Codiva, click Create Account situated at the top-right corner to commence the registration process.
Specify a project name and click Create. This action initiates the creation of a new project, essentially serving as a container for your source files.
Create a Java source file and click Create. Java source files must conclude with the .java file extension. The newly created file will be displayed within the project's tree, located in the right panel.
- For instance, if you're crafting a Java program named HelloWorld, designate the source file as HelloWorld.java.
Input or paste your code into the editor. The code undergoes compilation in the background as you input. Moreover, any encountered code errors are promptly displayed.
Press Run to execute the program. As the code automatically compiles, clicking Run initiates the execution of your application in its current form.
