Thread: doubt on synchronized block-2

the general form of synchronized block is

class table 
{ 
......
.
 void printTable(int n) 
{ 
synchronized(object)
 { 
...... 
} 
}
}

--------------------------------------------------------
here object means object of tble class or object of integer or sting... etc classes.
I want a programme which gets lock on object of string class or object of interger class.I mean the above object should be object of string class or object of integer class.
can any one give that programe.?
I request you to give that programme by editing below programme.
------------------------------------------------------------

import java.io.*;
class table
{
void printTable(int n)
{
synchronized(this)
{
for(int i=1;i<=5;i++)
{
System.out.println(n*i);
try{
Thread.sleep(500);
}
catch(InterruptedException ie)
{System.out.println(ie);
}
}
}
}
}
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);
}
}
class synchronizedblock1
{
public static void main(String args[]
)
{
table t=new table();
MyThread1 t1=new MyThread1(t);
MyThread2 t2=new MyThread2(t);
t1.start();
t2.start();
}
}

output:
