Program that checks if the number is prime or not finds 45 as a prime number

Question

Same thing happens when I type in number: 15,21,27,33 etc, basically every odd number divisible by 3.

Here's the code:

package com.company;

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter Number");
        int n = scanner.nextInt();

        for (int i = 2; i < n/2; ++i) {
            if (n % i == 0) {
                System.out.println("Not Prime");
                break;
            }
            else{
                System.out.println("Prime");
                break;
            }
        }
    }
}
