A loop for checking prime number

package pureTest;

import java.util.regex.*;

public class test3 {    
        public static void main(String[] args) {
            /* Enter your code here. */
            Scanner sc = new Scanner(System.in);
            int n = sc.nextInt();
            for (int i = 2; i< n; i++){
              if( n <= 3){
                  System.out.println("Prime");
                  break;
              }else if( n%i ==0){
                   System.out.println("Not Prime");
                   break;
              }else{
                  System.out.println("Prime");
              }
            }

          }
      }

the input of 7; the out put is repetitions of Prime:

7
Prime
Prime
Prime
Prime
Prime

Just wondering why the if condition doesn't work out here.
