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:

1. class TestMultiNaming1 extends Thread{  
2.   public void run(){  
3.    System.out.println("running...");  
4.   }  
5.  public static void main(String args[]){  
6.   TestMultiNaming1 t1=new TestMultiNaming1();  
7.   TestMultiNaming1 t2=new TestMultiNaming1();  
8.   System.out.println("Name of t1:"+t1.getName());  
9.   System.out.println("Name of t2:"+t2.getName());  
10.    
11.   t1.start();  
12.   t2.start();  
13.   
14.   t1.setName("Sonoo Jaiswal");  
15.   System.out.println("After changing name of t1:"+t1.getName());  
16.  }  
17. }  

Output:Name of t1:Thread-0
       Name of t2:Thread-1
       id of t1:8
       running...
       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:

1. class TestMultiNaming2 extends Thread{  
2.  public void run(){  
3.   System.out.println(Thread.currentThread().getName());  
4.  }  
5.  }  
6.  public static void main(String args[]){  
7.   TestMultiNaming2 t1=new TestMultiNaming2();  
8.   TestMultiNaming2 t2=new TestMultiNaming2();  
9.   
10.   t1.start();  
11.   t2.start();  
12.  }  
13. }  

Output:Thread-0
       Thread-1
