prime number in java
Solution
Sure, here is a simple way to check if a number is prime in Java:
public class Main {
public static void main(String[] args) {
int num = 29; // number to be checked
boolean flag = false;
for(int i = 2; i <= num/2; ++i)
{
// condition for nonprime number
if(num % i == 0)
{
flag = true;
break;
}
}
if (!flag)
System.out.println(num + " is a prime number.");
else
System.out.println(num + " is not a prime number.");
}
}
This program checks if a number (in this case 29) is a prime number or not. It does this by trying to divide the number by all numbers up to half of itself. If any of these divisions result in a remainder of 0, then the number is not prime. If none of them do, then the number is prime.
