Since all numbers are divisible by 1, we are avoiding it to save some computational time. Also the given number will always be divisible by 1 and N and we need not care, all we have to see is if any other between 1 and N divides N to prove its NOT PRIME.

It's great that u have noticed this, 0 and 1 are neither prime nor composite, for beginner level this program is fine. I really appreciate it, after roughly 5.8k views, u are the first person to notice. Just add this before the 'for' loop if(n == 0 || n == 1) { System.out.print("Neither prime nor composite"); System.exit(0); }
