In this section of java tutorial we will learn about the Java Thread setName() method and its use. Then We will create an example and show its usage.

• Java Thread setName() method sets the new name to each Thread.
• It is used in both Thread class and Runnable interface.
• Name is also set by the string data used in the constructor.

Java Thread setName Example

public class setname implements Runnable {
	@Override
	public void run() {
		System.out.println(Thread.currentThread());
	}

	public static void main(String[] args) {
		Thread t1 = new Thread(new setname(), "Thread a");
		t1.start();
		Thread t2 = new Thread(new setname());
		t2.setName("Thread b");
		t2.start();
		System.out.println(t1.getName());
	}
}

Output

Thread[Thread a,5,main] Thread a Thread[Thread b,5,main]
