a better approach. Make the immutable class itself final. Hence cannot make any sub classes, so no question of over ridding.
write code for user immutable class:-


final class ImmutableVenu{

private final int count;

private String phno="9742108000";

public ImmutableVenu(int paramCount,String paramPhno){

count=paramCount;

phno=paramPhno;
}

public int getCount(){
return count;
}

public String getString(){
return paramPhno;
}
}

public static void main(String ar[])
{

ImmutableVenu immu=new ImmutabeVenu();
s.o.p(immu.getCount());
s.o.p(immu.getPhno());
}
