How to create thread in java?

We can create thread by two methods:
       1.By extends
       2.By implements.

 Example:

class ByExtends extends Thread{ 
public void run()
    {
        System.out.println("thread is running...");
    }
public static void main(String args[]){ 
    ByExtends t1=new ByExtends(); //Create object of ByExtends class
    t1.start();  //start thread
 } 
}

Example:

public class ByImplements implements Runnable {
   
    public void run(){ 
        System.out.println("thread is running..."); 
        } 
         
        public static void main(String args[]){ 
        ByImplements m1=new ByImplements(); 
        Thread t1 =new Thread(m1); //passing class object in thread
        t1.start();  //start thread
         } 
        }

Multiple Thread:

Example:

public class MultipleThread implements Runnable{
   
    public void run(){
        System.out.println("The current Thread = "+Thread.currentThread().getName());
    }
     
}
 class Multithread{
    public static void main(String[] args) {
        MultipleThread mThread=new MultipleThread();
        Thread t1=new Thread(mThread);
        Thread t2=new Thread(mThread);
        Thread t3=new Thread(mThread);
        t1.start();
        t2.start();
        t3.start();
       
    }
}
