这段java代码出了什么问题

import java.util.Arrays;

public class mark {

    public static void main(String[] args) {

        int [] scores = {89,-23,64,91,119,52,73};

        mark hello = new mark();

        hello.handleGrade(scores);
    }
    public void handleGrade(int [] a){
        
        int num = 0;

        int [] three = new int [3];

        Arrays.sort(a);

        for (int i = a.length-1;i >= 0;i--) {
            if (a[i] > 100 || a[i] < 0) {
                continue;
            }
            else{
                three[num] = a[i];
                num++;
            }
            if (num==3) {
                    System.out.println("考试成绩的前三名 : " + Arrays.toString(three));
            }
        }
    }
}
