Not exactly sure whats wrong? What does it mean by not matching pattern? The program runs fine, would appreciate any help, thanks in advance.

import java.util.Scanner;

public class GradesAndPoints {

public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    
    int input1;
    System.out.println("Give points {0-100}: ");
    input1 = scanner.nextInt();
    if (input1 < 0) {
        System.out.println("impossible!");
    } else if (input1 <= 49) {
        System.out.println("failed");
    } else if (input1 <= 59) {
        System.out.println("1");
    } else if (input1 <= 69) {
        System.out.println("2");
    } else if (input1 <= 79) {
        System.out.println("3");
    } else if (input1 <= 89) {
        System.out.println("4");
    } else if (input1 <= 100) {
        System.out.println("5");
    } else if (input1 > 100) {
        System.out.println("incredible!");
    }
    
 
         
}

}
