How to make for loops in Java increase by increments other than 1

Question

If you have a for loop like this:

for(j = 0; j<=90; j++){}

It works fine. But when you have a for loop like this:

for(j          


        

Answer 1

In your example, j+=3 increments by 3.

(Not much else to say here, if it's syntax related I'd suggest Googling first, but I'm new here so I could be wrong.)
