Naming a thread:

The Thread class provides methods to change and get the name of a thread. public String getName(): is used to return the name of a thread. public void setName(String name): is used to change the name of a thread.

Example of naming a thread:

class TestMultiNaming1 extends Thread{  

  public void run(){  

   System.out.println("running...");  

  }  

 public static void main(String args[]){  

  TestMultiNaming1 t1=new TestMultiNaming1();  

  TestMultiNaming1 t2=new TestMultiNaming1();  

  System.out.println("Name of t1:"+t1.getName());  

  System.out.println("Name of t2:"+t2.getName());  

   

  t1.start();  

  t2.start();  

  

  t1.setName("Sonoo Jaiswal");  

  System.out.println("After changing name of t1:"+t1.getName());  

 }  

}  

Output:Name of t1:Thread-0
       Name of t2:Thread-1

       running...
id of t1:8

       After changeling name of t1:Sonoo Jaiswal

       running...

The currentThread() method:

The currentThread() method returns a reference to the currently executing thread object.


Syntax of currentThread() method:

public static Thread currentThread(): returns the reference of currently running thread.



Example of currentThread() method:


class TestMultiNaming2 extends Thread{  

 public void run(){  

  System.out.println(Thread.currentThread().getName());  

 }  

 }  

 public static void main(String args[]){  

  TestMultiNaming2 t1=new TestMultiNaming2();  

  TestMultiNaming2 t2=new TestMultiNaming2();  

  

  t1.start();  

  t2.start();  

 }  

}  






Output:Thread-0

       Thread-1
