Each value should be on a new line.

Requirements:

The program should display numbers on the screen.
The program should read values from the keyboard.
The Solution class must have two methods.
The sort() method should sort the array of numbers from highest to lowest.
The main() method should call the sort() method.
The program should display the five largest numbers in the array. Each value should be on a new line.

package com.codegym.task.task08.task0826; import java.io.BufferedReader; import java.io.InputStreamReader; import java.util.Arrays; /* Five winners */ public class Solution { public static void main(String[] args) throws Exception { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); int[] array = new int[20]; for (int i = 0; i < array.length; i++) { array[i] = Integer.parseInt(reader.readLine()); } sort(array); System.out.println(array[0]); System.out.println(array[1]); System.out.println(array[2]); System.out.println(array[3]); System.out.println(array[4]); } public static void sort(int[] array) { //write your code here int[] copy= array; Arrays.sort(copy); for(int i=0;i<copy.length;i++){ array[i]= copy[copy.length-1-i]; } } }

The problem is when you copy an int Array like you do, it's not actually a copy, but only a copy of the reference, that means when you assign new values to array[i] on line 33, you also assign these values in the copy array. To fix this, you can either use a loop to create a copy of the array, or use this:

int[] copy = array.clone();
