Java

Enterprise-grade object-oriented programming

Overview

Java is a widely-used, object-oriented programming language known for its 'write once, run anywhere' philosophy. With run, you can compile and execute Java code without managing complex project structures.

Basic Usage

Hello World

run java "public class Main { public static void main(String[] args) { System.out.println("Hello, World!"); } }"

Output

Hello, World!

REPL Behavior

Java's REPL maintains state across commands. Variables, classes, and methods persist within the same REPL session.
