please tell the mistake in my code

package com.codegym.task.task02.task0216;

/*
Minimum of three numbers

*/
public class Solution {
    public static int min(int a, int b, int c) {
        int d;
        if(a<=b&&a<=c)
        d=a;
        else if(b<=a&&b<=c)
        d=b;
        else if(c<=a&&c<=b)
        d=c;

        return d;
    }

    public static void main(String[] args) throws Exception {
        System.out.println(min(1, 2, 3));
        System.out.println(min(-1, -2, -3));
        System.out.println(min(3, 5, 3));
        System.out.println(min(5, 5, 10));
    }

}
