Java is one of the most widely used languages for backend services, Android apps and large systems. This workspace gives you a ready Java setup with the JDK installed, so you can write a class and run it from the terminal without configuring anything.
The JDK is installed and on your PATH. Run java Main.java to compile and run in one step, or use javac and java separately if you prefer.
The full cloud editor with an integrated terminal, the Java extensions and a debug config that ships in the .vscode folder.
Clone, commit and push from the terminal, or connect a GitHub repo whenever you're ready.
Boots in about a minute, with the JDK already in place so there's nothing to download first.
Java is a general-purpose, object-oriented language that compiles to bytecode and runs on the Java Virtual Machine. That bytecode runs the same way across operating systems, which is why Java has stayed a default choice for server-side software and enterprise applications for decades. It's also the original language for native Android development.
This workspace is a plain Java starter. It ships a single Main class that prints a greeting, so you have a working program to run from the first second and can grow it into whatever you're building.
The starter is one file, Main.java, with a standard main method that prints Hello, World!. The JDK is already installed, and the .vscode folder includes a launch configuration so you can run the Main class straight from the editor.
There's no build tool wired up by default, so this is the lightweight way to learn Java or work through exercises. If your project grows, you can add Maven or Gradle from the terminal and structure it into packages.
Open the terminal and run java Main.java. Recent JDKs let you launch a single source file directly, so it compiles and runs in one command. You can also do it the classic way with javac Main.java to produce Main.class, then java Main to run it.
To debug, use the launch config in the .vscode folder. Set a breakpoint in Main.java and start the Main configuration to step through your code.
Console programs, algorithm practice, data structures, command-line tools, or the starting point for a larger application once you add a build tool and dependencies. It's a clean base for learning the language or sketching out backend logic.
Open the terminal and run java Main.java. That compiles and runs the file in one step. You can also compile with javac Main.java and then run java Main if you'd rather keep the two steps separate.
Not by default. The template is a single-file starter so you can run code immediately. If you need dependency management or a multi-module layout, install Maven or Gradle from the terminal and add the usual build file.
Yes. The .vscode folder ships a Java launch config. Set breakpoints in Main.java and start it from the Run and Debug panel to step through your code in the cloud editor.
No, this template is a console program that prints to the terminal. If you want a web application with a browser preview, start from the Spring Boot template instead.
Yes. Create new .java files in the workspace and organise them into packages as your project grows. Compile them together with javac, or move to a build tool once the project gets bigger.
Java runs on a paid Studio plan. Templates that are free to launch are marked as such, and you can move to a paid plan from the pricing page to use this one.
