Difference between the for loops

Hi to every one..
This is ishmayel.. I am going to write complete my SCJP soon..

I had the following doubt regrading the for loop can any one help me please.

1. for( int i=0; i<3; i++)
{
System.out.print(i+"--");
}
out put is :: 0--1--2
2. for( int i=0; i<3; ++i)
{
System.out.print(i+"--");
}
out put is :: 0--1--2
I am thing that out put is like this.... :: 1--2

my question is why I am getting the same output in both conditions...
If both loops are the same than what is the difference between the
for( int i=0; i<3; i++) and for( int i=0; i<3; ++i)
I hope any one may help me soon.
Thanks in Advance..

hi,
Both are same in this case.Difference between post increment and pre increment is for example if you have x=0,y=0

case 1:
int i=++x; the value of i is 1.
case 2:
int i=x++; the value of i is 0 and after using x,it's value is incremented that is x=1.

Hi Naveen kumar..
thanks for your response..

I know the difference between the pre and the post increment/decrement
but why here in Both conditions I am getting the same output.
1.for( int i=0; i<3; i++)
2. for( int i=0; i<3; ++i)

Please explain write in detail.
Thanks in Advance..

Hi,
The reason is the way the for loop exceutes
1)Variable is intialized and then comparison is done
eg in this case
i will be initialized to 0 and then compared to value 3 ,since it is less than 3 it goes inside loop and prints value

2)After that it goes to increment part and and increases it by 1 and checks the condition again goes to print statement .So the result in both cases remain same
