Synchronization means only one thread can use the method at a time.
synchronized keyword is used to avoid data conflict.
import java.lang.*;
class Table
{
// synchronized method
synchronized void printTable(int n)
{
for(int i = 1; i <= 5; i++)
{
System.out.println(n + " x " + i + " = " + (n*i));
}
}
}
// Thread 1
class MyThread1 extends Thread
{
Table t;
MyThread1(Table t)
{
this.t = t;
}
public void run()
{
t.printTable(5);
}
}
// Thread 2
class MyThread2 extends Thread
{
Table t;
MyThread2(Table t)
{
this.t = t;
}
public void run()
{
t.printTable(10);
}
}
class SyncDemo
{
public static void main(String args[])
{
Table obj = new Table();
MyThread1 t1 = new MyThread1(obj);
MyThread2 t2 = new MyThread2(obj);
t1.start();
t2.start();
}
}
