Thread output

[sumit kothalikar]

see the following code

   

/*Programer :Sumit Kothalikar*/

class TestSynchronize{

public synchronized void m1(){
int [] a = {2,34,5,6,7,8,9};
for(int x:a){
System.out.println(a);
}

}


public static void main(String [] args){

final TestSynchronize mt = new TestSynchronize();

new Thread( new Runnable(){ public void run(){mt.m1();}}).start();

}
}


 

and the output is

[I@42e816
[I@42e816
[I@42e816
[I@42e816
[I@42e816
[I@42e816
[I@42e816

Why the output is not
2
34
5
6
7
8
9

Is it because i have marked mt ref variable as final or is it because m1() method is synchronized.

In m1 method, you are displaying the array a in the loop not the loop variable x. Since a is a local array, there are no synchronization issues. Each call to the m1 method will have a separate copy of a array...

None of those. Closely check what exactly you are printing inside the "System.out.." statement

you are right i am printing array object reference.
