Huh, some Java IDEs understand Console the same way!

School begins Monday for our local grade-schoolers,
are you sure you're in a summer class?

import javax.swing.JOptionPane;

public class DriverSort {

   public static void main(String[] args) {

     Object[] sorts = {"Insertion", "Selection", "Bubble"};

     String sortString = (String)JOptionPane.showInputDialog(
       null,
       "Select a sort algorithm\nCancel quits the program",
       "Sort Algorithm Selector",
       JOptionPane.PLAIN_MESSAGE,
       null,sorts,"Insertion");

     if(sortString == null) {
       System.exit(1);
     } else if(sortString != "Insertion"){
       JOptionPane.showMessageDialog(
           null, "Selection and Bubble sorts are not implemented");
       System.exit(2);
     }

     String arrayString = (String)JOptionPane.showInputDialog(
         null,
         "Enter a space separated list of integers\nCancel quits the 
program",
         "The Array to Sort"
         ,JOptionPane.PLAIN_MESSAGE,null,null,"");

     if(arrayString == null) {
       System.exit(3);
     }

     try {
       String[] stringArray = arrayString.split(" ");
       int[] input = new int[stringArray.length];
       for (int i = 0; i < stringArray.length; i++) {
         input[i] = Integer.parseInt(stringArray[i]);
       }
       Sorter.insertionSort(input);
       Sorter.printArray(input);

     } catch (NumberFormatException e) {
       JOptionPane.showMessageDialog(

       System.exit(4);

   }
