Button Name

Question

Button newbutton = new Button(string); Java automatically assignes a name to each of these buttons that are created in my app. (button0 - button16) There is a way to get their names but I forget. I tried getName() but that just returns the name of the frame that they are in. What is the correct statement to use?
full code:
class ButtonPanel extends TopPanel
          public ButtonPanel(String A)
               int strA = Integer.parseInt(A);
               int globalclasssize = strA;
               int gridSize = (int)( Math.ceil( Math.sqrt(globalclasssize) ));  //this line takes the sqrt of the number
               this.setLayout(new GridLayout(gridSize,gridSize));            // entered and rounds up to make a suitable grid.
               int idnum = 1;
               for(int num = 0; num<globalclasssize;num++)
                    int id = idnum++;
                    this.add( getButton("Desk " + id) );
                    this.add( getSpacer("") );
               this.setVisible(true);
          public Button getButton(String string)
               Button newbutton = new Button(string);
               newbutton.addActionListener(new java.awt.event.ActionListener()
                                   public void actionPerformed(java.awt.event.ActionEvent bevt)
                                             enterbActionPerformed();
               seatname = getName();
               System.out.println(seatname);
               return newbutton;
          public Button getSpacer(String string)
               Button newbutton2 = new Button(string);
               newbutton2.setVisible(false);
                 return newbutton2;
/* Action Events for Button */
public void enterbActionPerformed()
    seatname = getWHATGOESHERE();
    System.out.println(seatname);
}

Answer 1

The information you need to identify the button that generated the action event is in the event object bevt. If you're going to use another method for the actionPerformed() method body you must send along the event object:
public void actionPerformed(ActionEvent e) {
  enterbActionPerformed(e);Here's a way to get the button id in actionPerformed:
public void actionPerformed(ActionEvent e) {
  Button button = (Button)e.getSource();
  String ac = button.getActionCommand();
  // if you had declared the button names, eg, Button Desk1, Desk2,...;
  // then you could use
  if(button == Desk1) {
    // what to do when Desk1 is pressed
  // another way is to use the action command
  // there is a caveat with this approach: if your code gets translated
  // into another language the text on the buttons will change which
  // will change the action commands, unless you set them explicitly
  // (this is a bit tricky the way you wrote your code)
  if(ac.equals("Desk1")) {
    // carry on
  // to set the action command
  newbutton.setActionCommand(string);
  // in getButton()
