Numbers -- Prime Number
Write a method that can check if a number is prime or not
Solution:
public static boolean primeNumber(int num) {
if(num <= 1){
return false;
}
for(int i = 2; i < num; i++) {
if(num % i == 0) {
return false;
}
}
return true;

a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11)
suppose a number 'n' it can be divided by if '1' and only by itself then it can be a prime numberCopyright © 2021 Codeinu
