Question

I want to allow the user to enter any number of numbers and have them placed into an int array. I have been trying to use the max method but I am certain that I am not doing it right. This is part of a much bigger assignment to manipulate the input in the array with sort and search, but I cant even get the input right to test the array. This is the code I have been trying to use:

import java.util.Scanner;

public class NumbersArray
{
   public static void main(String [] args)
   {
      System.out.print("Enter Numbers with a single space between each number: ");
      Scanner keyboard = new Scanner(System.in);
      int num = keyboard.nextInt();
      while(keyboard.nextInt());
      {
         int num = keyboard.nextInt();
      }
   }
      public static int max(int... num)
      {  
         if (num.length == 0)
         {
            System.out.println("Fatal Error: no values entered.");
         }
      }
      {
         int numbers = num[0];
         for (int i = 1; i < num.length; i++)
            if (arg [i] < largest)
               numbers = arg[i];
         return numbers;
      }
      System.out.println(numbers);
   }
}

Explanation / Answer

i would suggest you to use list for this as array is not good for this type of implementation.
for array you can use this code
