Re: Difference ++j and J++
j++ returns the value of j then increments j.
++j increments the value of j then returns the value of j.
Can you work out why you're getting the different results now?

Hi helloworld922
Thank you for your quick response. Yes i managed to understand.
int j = 0;
while (j++ < 2) // j = 0 / j = 1/ j = 2 and condition false.
System.out.print(j); // prints incremented value. so J is 1/ J is 2,
int j = 0;
while (++j < 2) // j = 1/ j = 2 and condition false
System.out.print(j); // prints incremented value. so J is 1.

If you want to study more about these, google for Post Fix and Pre Fix Increment. You will get the clear understanding about these.

Re: Difference ++j and J++
j++ return the value of j after that it will make increment
while ++j return from incremented value
