what should i do

Question about the task

Minimum of four numbers

Java Syntax, Level 2, Lesson 8

Under discussion

i just cant do it

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.

Requirements:

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) { 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)); } }

Too complex. Read the requirement that you failed to do. Call method min(a, b) in min(a, b, c, d) Declare the integer variable 'minimum' in the beginning of method min(a, b, c, d) and at the end you return the value 'minimum'. Between these two lines of code, you call the method min(a, b) HINT : you call the method min(a, b) "several times"
