why its output is zero?

Question

int j=0;
for(int i=0;i<100;i++)
j=j++;
System.out.println(j);

Answer 1

Why don't you just save it in the code playground and run it? :)

Answer 2

To explain, you're assign j++ to j, instead of only putting j++. As such, each loop it's reassigning j++ to the variable j, so it never goes anywhere, thus it remains 0.

Do this instead:

int j=0;
for(int i=0;i<100;i++)
j++;
System.out.println(j);

99 is the answer as the loop will go on and there are no curly brackets therefore the value of j will keep on increasing as it is in the loop and the loop goes on till 99 therefore the output will be 99
