Accessing Shared Variable

AIM: the main aim this program is to use a Synchronized method to lock an object for any shared resource.

Source Code:

class Table{ 

 synchronized void printTable(int n){//synchronized method 

   for(int i=1;i<=5;i++){ 

     System.out.println(n*i); 

     try{ 

      Thread.sleep(400); 

     }catch(Exception e){System.out.println(e);} 

   } 

 } 

} 

 class MyThread1 extends Thread{ 

Table t; 

MyThread1(Table t){ 

this.t=t; 

} 

public void run(){ 

t.printTable(5); 

}  

} 

class MyThread2 extends Thread{ 

Table t; 

MyThread2(Table t){ 

this.t=t; 

} 

public void run(){ 

t.printTable(100); 

} 

} 

public class TestSynchronization2{ 

public static void main(String args[]){ 

Table obj = new Table();//only one object 

MyThread1 t1=new MyThread1(obj); 

MyThread2 t2=new MyThread2(obj); 

t1.start(); 

t2.start(); 

} 

}
