PLEASE.. how do I use the second min(int a, int b) in the first min(int a, int b, int c, int d)

THE SOLution package de.codegym.task.task02.task0217; /* Minimum of four numbers */ public class Solution { public static int min(int a, int b, int c, int d) { int m; if (min(a,b) <= b && a <= c && a <= d) m = a; else if (b <= a && b <= c && b <= d) m = b; else if (c <= a && c <= b && c <= d) m = c; else m = d; return m; } public static int min(int a, int b) { int m1; if (a <= b) m1 = a; else m1 = b; return m1; } 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)); } }

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) { //write your code here if(min(a,b)>c&& d >c){ return c; } if(min(a,b) > d && c >d){ return d; }else { return min(a,b); } } public static int min(int a, int b) { //write your code here if(a>b){ return b; }else{ return a; } } 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)); } }

check your personal message. you will get the solution.

You can use it like this: public static int min(int a, int b, int c, int d) {return min(min (a, b), min (c, d));}

In real life, there are many methods to find the minimum of a, b, c, d. one example is to look through the number from left to right : * find the minimum of a and b => let's call it "min1" * find the minimum of "min1" and c ==> let's call it "min2" * find the minimum of "min2" and d ==> that's the minimum !

get minimum of first two numbers in min(a,b,c,d) function and pass the remaining two as arguments by calling min(a,b) function..calculate minimum of these two there and then compare returned value against minimum value of previous two numbers.
