Thread Class static Thread currentThread()

• This method is available in package java.lang.Thread.currentThread().
• This method is used to return a reference of the currently executing thread object.
• This method is static so this method is accessible with classname too.
• The return type of this method is Thread, it returns a reference of currently executing thread object.
• This method does not raise any exception.

Syntax:

    static Thread currentThread(){
    }

Parameter(s):

We don't pass any object as a parameter in the method of the File.

Return value:

The return type of this method is Thread, it returns reference of current executing thread.

Java program to demonstrate example of currentThread() method

/*  We will use Thread class methods so we are importing 
    the package but it is not mandate because 
    it is imported by default
*/

import java.lang.Thread;

class Thread1 extends Thread {
    // Override run() of Thread class
    public void run() {
        /*  Display a thread name of current executing thread 
            by using Thread.currentThread().getName()
        */
        System.out.println("The name of this thread is " + " " + Thread.currentThread().getName());
    }
}

class Thread2 extends Thread {
    public void run() {
        /*  Display a thread name of current executing thread by 
            using Thread.currentThread().getName()
        */
        System.out.println("The name of this thread is " + " " + Thread.currentThread().getName());
    }
}

public class MainThread {

    public static void main(String[] args) {

        /*  Display a thread name of current executing thread by 
            using Thread.currentThread().getName()
        */
        System.out.println("The name of this thread is " + " " + Thread.currentThread().getName());

        // Creating Thread1 object
        Thread1 t1 = new Thread1();

        // By using start() Thread class start() will call and 
        // it will call run() of Thread1 class
        t1.start();

        Thread2 t2 = new Thread2();

        // By using start() Thread class start() will call 
        // and it will call run() of Thread2 class
        t2.start();
    }
}

Output

E:\Programs>javac MainThread.java

E:\Programs>java MainThread
The name of this thread is  main
The name of this thread is  Thread-0
The name of this thread is  Thread-1
