Why not write i ‹ 5?
Short answer. If the array size changes, the loop breaks. m.length always matches.
Does an array's length need brackets?
No. Only a String uses length().
Remember
| Loop while i < m.length |
| Array length has no () |
Your loop says less than five. What if the array grows? Use M dot length instead. The loop visits every box. Next int reads a number into each. Remember. Loop up to length. Array length has no brackets.
