MULTI THREADING

MULTI THREADING

Aim:

            To write a java program to implement multithreading.

  Algorithm:

Step1: Start.

Step2: Define a class A that extends Thread.

Step3: Call run(). Within this , use for loop to display the value of I from  to 5.

Step4: Define a class B that extends Thread.

Step5: Call run() to display the value of j from 1to 10.

Step6: Define class C that extends Thread.

Step7: Call run() to display the value of k from 1 to 15.

Step8: In the main() call A, B, C classes using start() with the help of an object.

Step9: Stop.

Program:

class A extends Thread

{

public void run()

{

for(int i=1;i<=5;i++)

{

System.out.println("from Thread A:i="+i);

}

System.out.println("Exit from A");

}

}

class B extends Thread

{

public void run()

{

for(int j=1;j<=10;j++)

{

System.out.println("from Thread B:j="+j);

}

System.out.println("Exit from B");

}

}

class C extends Thread

{

public void run()

{

for(int k=1;k<=15;k++)

{

System.out.println("from Thread C:k="+k);

}

System.out.println("Exit from C");

}

}

class ex1

{

public static void main(String args[])

{

new A().start();

new B().start();

new C().start();

}

}

OUTPUT:
