Use the min(a, b) method??

public class Solution { public static int min(int a, int b, int c, int d) { //write your code here

//TRY THIS PLSE package com.codegym.task.task02.task0217; /*

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 int m=min(a,b); int n=min(c,d); int q=min(m,n); return q; } public static int min(int a, int b) { //write your code here if(a<b) return a; else return b; } 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)); } }

There are 2 methods here: 1) min() method taking 2 integers as argument and returning the minimum of those 2 integers. 2) min() method taking 4 integers as argument and returning the minimum of those 4 integers. Now, firstly we should write the code for min() method taking 2 integers as argument. Then we should write the other min() method which takes 4 integers as arguments, HERE we can call the above written code so that 4 integers can be divided into 2 groups and minimum of both of them will be calculated by calling the above written code.The syntax for calling the above method is:- public static int min(int a, int b, int c, int d) { int m4; // here we will store the minimum among 4 integers int test1 = min(a,b); /* THIS is the step where we are sending a and b to the other min method(which takes 2 integers for calculating its minimum value*/ int test2 = min(c,d); /* THIS is the step where we are sending c and d to the other min method(which takes 2 integers for calculating its minimum value*/ if (test1<=test2) { /* THIS is the step when we now calculate the minimum among test1 and test2 thus resulting in the minimum of all 4 integers. m4 = test1; } else { m4 = test2; } return m4; }

You have 4 numbers. If you get result from min(a, b) for first 2 number, and then use this method for other 2 number, you will have two minimum number from 4. And then use min(a, b) to remaining numbers
