Why is this the outcome?

Question

The outcome of this code is 012024, but I really don't understand why. Could someone explain it to me?

for(int i = 1; i < 3; i++){
for(int j = 0; j < 3; j++){
if(i + j > 5)
break;
System.out.print(i*j);
}
}

Answer 1

1st outer loop:
1st inner loop: i=1, j=0, i*j=0
2nd inner loop: i=1, j=1, i*j=1
3rd inner loop: i=1, j=2, i*j=2
4th inner loop: j would no longer be <3, so the requirement is not fulfilled

2nd outer loop:
1st inner loop: i=2, j=0, i*j=0
2nd inner loop: i=2, j=1, i*j=2
3rd inner loop: i=2, j=2, i*j=4
4th inner loop: same as above

3rd outer loop: requirement is not fulfilled, so your program will not enter the inner loop anymore and your break-condition is never reached!
So your program is done.

Answer 2

1. i=1, j=0 . Here i+j is not > 5, Hence break is not executed. i*j is printed = 0

2. i=1 j=1 same blah blah, i*j = 1 . NET OUT= 01

3. i=1, j= 2 same blah blah , i*j = 2 NET OUT=012
Inner Loop terminated,outer incremented

4. i=2 j=0 same , i*j=0 NET = 0120

5 i=2 j=1 same , i*j = 2 net=01202

6. i=2 j=2 same , i*j =4 net = 012024
inner terminated, outer terminated.

Loops terminated.

Answer: 012024

If statement never works.

Thanks, it all makes sense now!
