What did i do wrong?

Question about the task

Minimum of four numbers

Java Syntax, Level 2, Lesson 8

Resolved

I still doesnt quite understand how i connect the two methods together.

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 smallest = a; if (smallest > b) smallest = b; if (smallest > c) smallest = c; if (smallest > d) smallest = d; return smallest; } public static int min(int a, int b) { int smallest1 = a; if (smallest1 > b) smallest1 = b; return smallest1; } 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)); } }

solution

Instead of this,

int smallest = a;

call:

int smallest = min(a,b);

then you can do away with some bits of your code.
