Thread Class Methods Use Example

Example:

The following ThreadClassDemo program demonstrates some of these methods of the Thread class:

// File Name : DisplayMessage.java // Create a thread to implement Runnable public class DisplayMessage implements Runnable {    private String message;    public DisplayMessage(String message)    {       this.message = message;    }    public void run()    {       while(true)       {          System.out.println(message);       }    } } // File Name : GuessANumber.java // Create a thread to extentd Thread public class GuessANumber extends Thread {    private int number;    public GuessANumber(int number)    {       this.number = number;    }    public void run()    {       int counter = 0;       int guess = 0;       do       {           guess = (int) (Math.random() * 100 + 1);           System.out.println(this.getName()                        + " guesses " + guess);           counter++;       }while(guess != number);       System.out.println("** Correct! " + this.getName()                        + " in " + counter + " guesses.**");    } } // File Name : ThreadClassDemo.java public class ThreadClassDemo {    public static void main(String [] args)    {       Runnable hello = new DisplayMessage("Hello");       Thread thread1 = new Thread(hello);       thread1.setDaemon(true);       thread1.setName("hello");       System.out.println("Starting hello thread...");       thread1.start();             Runnable bye = new DisplayMessage("Goodbye");       Thread thread2 = new Thread(hello);       thread2.setPriority(Thread.MIN_PRIORITY);       thread2.setDaemon(true);       System.out.println("Starting goodbye thread...");       thread2.start();       System.out.println("Starting thread3...");       Thread thread3 = new GuessANumber(27);       thread3.start();       try       {          thread3.join();       }catch(InterruptedException e)       {          System.out.println("Thread interrupted.");       }       System.out.println("Starting thread4...");       Thread thread4 = new GuessANumber(75);                   thread4.start();       System.out.println("main() is ending...");    } }

This would produce following result. You can try this example again and again and you would get different result every time.

Starting hello thread... Starting goodbye thread... Hello Hello Hello Hello Hello Hello Hello Hello Hello Thread-2 guesses 27 Hello ** Correct! Thread-2 in 102 guesses.** Hello Starting thread4... Hello Hello ..........remaining result produced.
