    Default Arrays & Methods

    Ok what I have is the main method where a user inputs how many numbers they want to input in the next section, this works fine and so does inputting the numbers but how do I print the array out and process the array from method to method?

    Code is below

    Java Code:
    import javax.swing.*;
    public class Arrays
    {
    	public static void main(String[] args)
        {
        	String amount = JOptionPane.showInputDialog(
                       "Enter a number");
            int n = Integer.parseInt(amount);
        	int[] numbers = new int [n];
        	getNumbers(n);
        	
        	for (int i = 0; i < n; i++)
            {
            	System.out.println(i + "\t" + numbers[n]);
            }
        }
    
        public static int getNumbers(int n)
        {   
        	while(n > 0)
        	{
        	String inputNumber = JOptionPane.showInputDialog(
                       "Enter a number");
            int number = Integer.parseInt(inputNumber);	
            n--;
       		}
        return n;
        }

    Default

    do int[] numbers; outside your main method. then inside do numbers = new int[n]

    that will make your array accessable throughout the program.

    to print it out write a for loop from 0 to array.length
