    frame.add(new JButton());

    And you canuse setActionListener() and setActionCommand() to set it up to detect it being pressed.

    If you are using a JFrame, you should make the call to (assuming your JFrame is named frame)

    frame.getContentPane().add(new JButton());

    In most circumstances you would add the JButton to a JPanel, along with any other things necessary (in your case perhaps a JLabel with a message?), then add that JPanel to the content pane, and as Freaky Chris describes add an action listener to the button to lister for events.

    this one..

    public class SwitchSample4_EnumType {
     
        private static enum Day {
     
            MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY
        }
     
        public static void main(String[] args) {
     
            Day day = Day.values()[new Random().nextInt(Day.values().length)];
     
            switch (day) {
     
                case MONDAY: 
     
                    System.out.println("Its Monday");
                    break;
     
                case TUESDAY:
     
                    System.out.println("Its Tuesday");
                    break;
     
                case WEDNESDAY:
     
                    System.out.println("Its Wednesday");
                    break;
     
                case THURSDAY:
     
                    System.out.println("Its Thursday");
                    break;
     
     
                case FRIDAY:
     
                    System.out.println("Its Friday");
                    break;
     
                case SATURDAY:
     
                    System.out.println("Its Saturday");
                    break;
     
                case SUNDAY:
     
                    System.out.println("Its Sunday");
                    break;
     
                default:
     
                    System.out.println("what day is it?");
                    break;

    Here is, in my opinion, the most interesting part:
    JAVA Code:

    //If first time key in date run statement
    if(first == 0){
    ++first;//Track if is the first record key in
    items[i] = new Item(itemNumber, itemDesc, sellPrice, quantity);
    }
    //Else continue key in record
    else{
    entries = items[0].getEntries();//Get number of entries entered
    for(j=0; j<entries; ++j){

    duplicate = items[j].equals(itemNumber, itemDesc, sellPrice, quantity);//Check for duplication of entries

    if(duplicate == true) {
    Print.duplicateError();
    --i;
    --looping;
    break;
    }
    }
    if(duplicate == false)//else save record
    items[entries] = new Item(itemNumber, itemDesc, sellPrice, quantity);
    }
