Hello,

i need your help, i don't understand the output of this code. Can you help me please ?

<CODE>
class Parent
{
private void method1() // the method is private
{
System.out.println("Parent's method1()");
}
public void method2()
{
System.out.println("Parent's method2()");
System.out.println(this);
method1();
}
}

class Test extends Parent
{
public void method1()
{
System.out.println("Test's method1()");
}
public static void main(String args[])
{
Parent p = new Test();
p.method2();
}
}
</CODE>

I have this as output in my computer :

Parent's method2()
Test@18d107f
Parent's method1()

I think, it shoul be :

Parent's method2()
Test@18d107f
<BOLD> Test's method1() </BOLD> because the object executing method2() is Test@18d107f

Thank you very much.

I have another question if i delete the notify() method in class ThreadB i have the same result. I thought that without notify in class ThreadB, the class ThreadA will still wait. ThreadA complete his synchronized code without any problems.

Do you have any answer for this question ? Thank you.

hi,

I need your help, I don't understand the way this code works.
I thought that after writting b.start(); the code within the run() method
will be excuted.But it's excuted only later in synchronized.why ?






This is the output :

total value before the start method :0
total value after the start method :0
Waiting for b to compl�te ..
***********In the run method****************
After the wait
Total is : 4950
***************End of the run method******************
total value in synchronized method :4950

I have looked for in the old posts and i find one about this problem but the answer wasn't clear. Thank you for your help.

Hi,

I don't really understand how the toString method is used in the code below :

One of the possible result :


Initial State: [k, q, i, j, f, V, J, S, c, v, u', U, C, z, I, y, d, H, X, e]
Sorted: [C, H, I, J, S, U, V, X, c, d, e, f, i, j, k, q, u', v, y, z]
Reversed: [z, y, v, u', q, k, j, i, f, e, d, c, X, V, U, S, J, I, H, C]



I don't see any place where the toString method is called. But if i put it in commentary the result is not the same. Can someone help me, please ? thank you.

Ps : I take the code on the cd of the book "complete java 2 certification", in solution of the chapter 8.
Thank you to everyone for your answer. I thought that the equals method was the same for Object, Integer,.. and so one. But i was wrong. thank you !!!
Hi everybody,
Can anyone explains the result of this code :

public class Reference {
public static void main (String Args [] ){
Reference t1 = new Reference ();
Reference t2 = new Reference ();

if (t1.equals(t2)){
System.out.println ("Same content");
}else{
System.out.println ("Different content");
}
}
}
the output is : Different content. I thought it would be Same content.
Thank you
