Simple nested for loop example

Question

Currently I am studying for my Java test. Whist studying I\'ve come across a small problem.

In this for loop:

for ( int i=1; i <= 3 ; i++ ) {
            


        

Answer 1

Each iteration of i, you're starting a completely new iteration of j.

So, you start with i==1, then j==1,2,3 in a loop. Then i==2, then j==1,2,3 in a loop, etc.

Step through it one step at a time, and it will make sense.
