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

If you have a for loop like this:

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

In this loop you are using shorthand provided by java language which means a postfix operator(use-then-change) which is equivalent to j=j+1 , so the changed value is initialized and used for next operation.

for(j = 0; j<=90; j+3){}

In this loop you are just increment your value by 3 but not initializing it back to j variable, so the value of j remains changed.
