    Default Stuck :(

    I'm trying to create a program that asks a user to enter 5 numbers and prints the highest number entered.

    So far i have:
    import java.util.Scanner;
    import java.io.*;
    import java.io.IOException;
    import java.util.*;
     
    public class arrayNum
    {
     
           public static void main(String[] args)throws IOException{
     
                    Scanner input = new Scanner(System.in);
                    int array[] = new int[5];
                    int count=0;
                    int numbers;
     
     				System.out.println("Please enter 5 numbers");
     
                    {
                    while (count < 5)
                    {
    				numbers = input.nextInt();
    						count++;
     
                    }
     
     
    				}
     
     
    {
     
    				int max = array[5];
     
    				for(int i = 0; i < array.length; i++)
    				{
     
    				 if(array[i] > max)
    				 {
     				 	max = array[i];
    				 }
    			 	}
    }
     
     
     
     
     
     
     
    System.out.println("Largest number is:  " + max  );
     
    										}
    }
    Any help will be greatly appreciated!

    Regards
    Rob.

    The reason your program is failing is because Java arrays start from 0, not 1. So, when you try to reference array[5], you are really trying to access the 6th element of the array. This of course doesn't exists, and Java will tell you so. Simply change it to any valid index for the array (I'll leave this up to you now that you know where to look).

    Darryl, please keep it respectful. Helping in this case is completely acceptable because it is a simple error and they have shown that they have tried to solve the problem themselves.
