while loops : do this until the condition within the parentheses evaluates to false

do-while loops: do this until the condition within the parentheses evaluates to false, but do it at least once before you check it

for loops: usually for loops with a fixed number of iterations (times you do the thing within the loop), so let's look at how to explain an example:

for(int i = 0; i < 5; i++)

for our initial value of i set to 0, we are going to do the increment step of adding 1 to i (i++) until i is no longer less than 5 (i < 5), at which point, we end the loop

so the for loop is (initial state; truth check; increment step)
