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

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

}

j+3 will not assign the new value to j, add j=j+3 will assign the new value to j and the loop will move up by 3.

j++ is like saying j = j+1, so in that case your assigning the new value to j just like the one above.
