• Create a function to check if a number is prime by iterating from 2 to the square root of the number.

• If the number is divisible by any number in that range, it is not prime.

• Handle edge cases like 0, 1, and negative numbers separately.

• Example: public static boolean isPrime(int num) { for(int i=2; i<=Math.sqrt(num); i++) { if(num % i == 0) { return false; } } return tru
