//Example: establishing and starting two threads Public classThreadTestImplementsrunnable{ Public Static voidMain (string[] args) {ThreadTest runner=NewThreadTest ();//Create an instance of RunnableThread alpha=NewThread (runner); Thread Beta=NewThread (runner);//Create two threads, using the same runnable, i.e. the same taskAlpha.setname ("Alpha thread")); Beta.setname ("Beta thread");//take a name for a threadAlpha.start (); Beta.start ();//Start Thread} @Override Public voidrun () { for(inti=0;i<25;i++) {String threadname=Thread.CurrentThread (). GetName (); System.out.println (ThreadName+ "" +i+ "is running"); }    }    }

Output Result:

Beta Thread 0 is running
Beta Thread 1 is running
Alpha Thread 0 is running
Alpha Thread 1 is running
Alpha Thread 2 is running
Alpha Thread 3 is running
