Hello java pros and experts, the first problem I have is implementing a code into my program where it tells a user "No numbers were entered" when they do not enter any numbers and the array is empty.
the second problem I have is implementing a code if the user enters too many numbers, put out an Error message that the size of the array has been exceeded; then print out the numbers entered on the next line.
This is my code so far:
import java.util.Scanner;
public class FunWithArrays
{
public static void main(String[] args)
{
final int ARRAY_SIZE = 10; // Size of the array
// Create an array.
int[] numbers = new int[ARRAY_SIZE];
// Pass the array to the getValues method.
getValues(numbers);
System.out.println("Here are the " + "numbers that you entered:");
// Pass the array to the showArray method.
showArray(numbers);
}
public static void getValues(int[] array)
{
// Create a Scanner objects for keyboard input.
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter a series of " + array.length + " numbers.");
// Read the values into the array
for (int index = 0; index < array.length; index++)
{
System.out.print("Enter the number " + (index + 1) + ": ");
array[index] = keyboard.nextInt();
}
}
public static void showArray(int[] array)
{
// Display the array elements.
for (int index = 0; index < array.length; index++)
System.out.print(array[index] + " ");
}
}
I was wondering if you pros or experts have any advice on how to approach this problem without changing any of the codes in my program? my professor instructed me to do a do-while loop for the problem, but do not know how to create the code for it... any suggestions?
