В чем проблема?

public class Solution {
    public static void main(String[] args) throws Exception {
        int a = Integer.parseInt(reader());

        int mid;
        int min;

        if (a >= b && a >= c) {
            max = a;
            if (b > c) {
                min = c;
                mid = b;
            }
            else {

                mid = c;
            }
        }
