🔥 Go vs Java: Concurrency Comparison (Goroutines vs Threads)
Concurrency is key in modern apps — let’s compare how Go and Java handle it!
---

🔹 Java
Java uses OS threads, created via Thread or managed using Executors.
Each thread is relatively heavy and context switching can be expensive.
Best for: Stable, enterprise-level multithreading with fine control.

// Java Concurrency
class MyThread extends Thread {
public void run() {
System.out.println("Hello from Java thread");
}
}
public class Main {
public static void main(String[] args) {
new MyThread().start(); // Starts a new thread
}
}
---

🔹 Go
Go was designed with concurrency at its core.
It uses goroutines which are extremely lightweight green threads, managed by Go’s runtime scheduler.
Goroutines use less memory and are great for high-performance concurrent tasks.

// Go Concurrency
package main
import "fmt"
func say(msg string) {
fmt.Println(msg)
}
func main() {
go say("Hello from Go goroutine") // Launch goroutine
fmt.Scanln() // Pause to allow goroutine to run
}

✅ Key Differences:
| Feature | Java | Go | |----------------|-------------------------|-----------------------------| | Thread Type | OS-Level | Lightweight (goroutine) | | Scheduler | OS (via JVM) | Built-in in Go runtime | | Communication | Shared memory + sync | Channels | | Overhead | High | Very Low |

🧠 Choose Go for simplicity and scale, Java for control and maturity!
