ive been stuck on this for multiple days and i just cant figure it out.

package com.codegym.task.task02.task0217;
/*
Minimum of four numbers
*/
public class Solution {
public static int min(int a, int b, int c, int d) {
int min;
if
(a <= b && a <= c && a <= d)
min = a;
else if
(b <= a && b <= c && b <= d)
min = b;
else if
(c <= a && c <= b && c <= d)
min = c;
else
min = d;
return min;
}
public static int min(int a, int b) {
int min;
if
(a <= b)
min = a;
else
min = b;
return min;
}
public static void main(String[] args) throws Exception {
System.out.println(min(-20, -10));
System.out.println(min(-20, -10, -30, -40));
System.out.println(min(-20, -10, -30, 40));
System.out.println(min(-40, -10, -30, 40));
}
}
