In bespreking

Write a function that computes the minimum of four numbers.
The function min(a, b, c, d) should use (call) the function min(a, b)

Hint:
You need to write the body of the two existing min functions.

Vereisten:

The program should display text on the screen.
The min methods should not display text on the screen.
The main method should call min(a, b) and min(a, b, c, d).
The main method should display the result of the min methods. Each time, on a new line.
The min(a, b) method must return the minimum of the numbers a and b.
The min(a, b, c, d) method must use the min(a, b) method.
The min(a, b, c, d) method must return the minimum of the numbers a, b, c, and d.

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) { if (min(a, b) < c) { return (min(a, b) <= d) ? min(a, b) : d; } else { return (c <= d) ? c : d; } } public static int min(int a, int b) { return (a <= b) ? a : 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)); } }

You can see it in the min of two method too.

public static int min(int a, int b) {
        return (a <= b) ? a : b;
    }

A brief formula to 'if {} else {} ' when you want to check simply things. This 2 below is the same:

public static int min(int a, int b) {
        return (a <= b) ? a : b;
    }

and

public static int min(int a, int b) {
        if (a <= b ) {
              return a;
        }
        else {
              return b;
        }

But i don't recommend to use it when your code grow bigger and more difficult, because that confusing, like this row:

return (min(a, b) <= d) ? min(a, b) : d;

... my first thoght was "what the f*ck is this piece of sh*t?"
