JAVA: syntax, commands, or what?

[TheTree]

Hi Everbody!

I'm just learning JAVA. I'm using Windows 98/JDK 1.3.1_08/DOS4.0.

1. I'm thinking I need an "implements ActionListener and an ItemListener in my main(), for the menu items; but, "it" doesn't like it---and/or, it doesn't like the way I'm, maybe, not followin'-through?!
2. I need a Status Bar. Couldn't I just use, something like " public statusBar extends JPanel { " ??
3. I need to know how to "talk" to, I guess, another object/class...
for instance, I need to know what command to use to make the menu items do what they're s'pose to. I tried putting:
public void actionPerformed(ActionEvent evt) {
String command = evt.getActionCommand();
if (command.equals("Red")) {
setBackground(Color.red);
}
else if (command.equals("Green"))
setBackground(Color.green);
else if (command.equals("Blue"))
setBackground(Color.blue);
else if (command.equals("Cyan"))
setBackground(Color.cyan);
else if (command.equals("Magenta"))
setBackground(Color.magenta);
else if (command.equals("Yellow"))
setBackground(Color.yellow);
etc, after drawCard Graphics---"it" didn't like it!!
4. I need a Right-click menu---I tried:
JPopupMenu popup; I put it right before " Image cardImages; " in the main()
then, I put:
popup = new JPopupMenu();
popup.add("Sort By Suit").addActionListener(this);
popup.add("Numerical Sort").addActionListener(this);
popup.add("Restore Card Order").addActionListener(this);
in class CardsHandsFrameCanvas---but, I just happened to think of something---I didn't put, something like:
setJPopupMenu(create popupMenu);
in the Constructor-----could that've been it??
5. I need to Drag-and-drop; I put:
Image clickedImage = null;
Image draggedImage = null;
int prevDragX;
int prevDragY;
public void mousePressed(MouseEvent evt) {
if (draggedImage != null) {
return;
}
if (evt.isPopupTrigger()) {
popup.show(this,x70,y70);
}
else {
// Start dragging the shape.
draggedShape = clickedShape;
prevDragX = x;
prevDragY = y;
}
}
in the class CardsHandsFrameCanvas; and, also:

public void mouseDragged(MouseEvent evt) { etc.
public void mouseReleased(MouseEvent evt) { etc.
and:
addMouseListener(this);
addMouseMotionListener(this);
after setBackground(Color.white); in the Constructor.
I don't THINK I got any/many errors on this part---I know I didn't get any, for puttin' addMouseListener(this); after the setBackground... part.
6. Right now, the errors I'm getting, are:
CardsHandsFrame.java:26: ';' expected
public JMenuBar create menuBar() {
^
CardsHandsFrame.java:16: cannot resolve symbol
symbol : constructor CardsHandsFrame (java.awt.image)
location: class CardsHandsFrame
CardsHandsFrame game = new CardsHandsFrame(cards);
^
2 errors
I've tried everything I can think of, to correct these errors.

I made a list of things I needed, then took them off the list, above, as I learned/implemented them; the remainder I posted, here. I thought that would be better than comin'-back SIX times!!Also, obviously, I took the program apart; posted the problem areas; and then, posted the shortest part of the program. With any of the items I've asked about, any help would be, GREATLY, appreciated!! I've taken a dozen (okay---maybe not a dozen) tutorials---I searched these forums---I have the API---java.sun.com drives me insane---I can't figure anything out...

A MILLION THANKS, in advance!!!
