could someone please point out what wrong with my code here? this is to find the maximum of 4 Use the keyboard to enter four numbers, and display the maximum of them. If the maximum occurs more than once, just display it once. Requirements: The program should read the numbers from the keyboard. The program must display a number on the screen. The program should display the maximum of four numbers. If there are several maximum numbers, display any of them. package com.codegym.task.task04.task0419; /* Maximum of four numbers */ import java.io.*; public class Solution { public static void main(String[] args) throws Exception { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); int a = Integer.parseInt(reader.readLine()); int b = Integer.parseInt(reader.readLine()); int c = Integer.parseInt(reader.readLine()); int d = Integer.parseInt(reader.readLine()); if (a>=b && a>=c && a>=d){ System.out.println(a); } if (b>=a && b>=c && b>=d){ System.out.println(b); } if (c>=a && c>=b && c>=d){ System.out.println(c); } if (d>=a && d>=b && d>=c){ System.out.println(d); } } }
