Go, Rust & Java Code Editor: Systems Programming Languages

Write code in Go, Rust, and Java - three powerful languages for systems programming, backend development, and high-performance applications. Our editor provides full syntax highlighting and support for all three languages.

Go (Golang)

Go is Google's language for building fast, concurrent, and scalable applications.

Key Features

• Simple syntax - easy to learn
• Built-in concurrency with goroutines
• Fast compilation
• Excellent for microservices

Go Example

package main

import (
    "fmt"
    "time"
)

func main() {
    // Goroutines for concurrency
    go printMessage("Hello")
    go printMessage("World")
    time.Sleep(time.Second)
}

func printMessage(msg string) {
    fmt.Println(msg)
}

Rust

Rust provides memory safety without garbage collection, perfect for systems programming.

Key Features

• Memory safety without GC
• Zero-cost abstractions
• Ownership and borrowing system
• Excellent performance

Rust Example

fn main() {
    let mut numbers = vec![1, 2, 3, 4, 5];
    
    // Ownership and borrowing
    let doubled: Vec<i32> = numbers
        .iter()
        .map(|x| x * 2)
        .collect();
    
    println!("{:?}", doubled);
}

Java

Java is the enterprise standard for building large-scale applications.

Key Features

• Platform-independent (Write Once, Run Anywhere)
• Strong typing and OOP
• Rich ecosystem and libraries
• Enterprise-grade features

Java Example

public class Calculator {
    private int result;
    
    public Calculator() {
        this.result = 0;
    }
    
    public int add(int value) {
        result += value;
        return result;
    }
    
    public static void main(String[] args) {
        Calculator calc = new Calculator();
        System.out.println(calc.add(10));
    }
}

When to Use Each Language

Choose Go When:

• Building microservices or APIs
• Need simple concurrency
• Want fast compilation
• Building CLI tools

Choose Rust When:

• Need maximum performance
• Building system-level software
• Memory safety is critical
• Working with WebAssembly

Choose Java When:

• Building enterprise applications
• Need extensive libraries
• Working with Android
• Team already knows Java

Syntax Highlighting

Our editor provides full syntax highlighting for all three languages:

• Keywords and operators
• Functions and methods
• Strings and comments
• Type annotations
• Bracket matching
