Java Naming Thread and Current Thread

Naming Thread

The Thread class provides methods to change and get the name of a thread. By default, each thread has a name, i.e. thread-0, thread-1 and so on. By we can change the name of the thread by using the setName() method. The syntax of setName() and getName() methods are given below:

We can also set the name of a thread directly when we create a new thread using the constructor of the class.

Example of naming a thread : Using setName() Method

FileName: TestMultiNaming1.java

Output:

Name of t1:Thread-0
Name of t2:Thread-1
After changing name of t1:Sonoo Jaiswal

Example of naming a thread : Without Using setName() Method

One can also set the name of a thread at the time of the creation of a thread, without using the setName() method. Observe the following code.

FileName: ThreadNamingExample.java

Output:

Thread - 1: JavaTpoint1
Thread - 2: JavaTpoint2
 The thread is executing....
 The thread is executing....

Current Thread

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

Example of currentThread() method

FileName: TestMultiNaming2.java

Output:

Thread-0
Thread-1
