Need Help reading errors

[sccot21]

Hey I am making a boardsquare for a chessboard thing is I do not know what is wrong with my program, everything looks fine to me. If someone could please help me with this i would surely appreciate it. my attachment button is not working so i have to put the code here.

import java.awt.*;

import javax.swing.*;



public class ChessPanel extends JFrame {

	 * creates a chess board piece and the square
	 * 
	 * @param frame
	 *           
	 */
	 public ChessPanel (JFrame myFrame) {
		 
		 BoardSquare myBoard = new BoardSquare ('f' , 4);
		 myBoard.setPreferredSize((new Dimension(350 , 350)));
		 myBoard.setBackground(Color.black);
		 
		 myFrame.getContentPane().add(myBoard);
		 myFrame.pack();
		 myBoard.setVisible(true);
		 
		 DummyPiece dummy = new DummyPiece();
		 myBoard.setPiece(dummy);
		 
		 myBoard.setSelected(true);
		 
		 }
	 
	 
	

}

}

Please someone help me.

That's an awful lot of code to have to sort through. Can you provide some details about what you are trying to accomplish, what the errors are that you are seeing? While you are thinking about what is wrong, maybe you can narrow down to specific areas in your code the problem might be.

[shall]

public class ChessPanel extends JFrame { //   ???

shouldn't ChessPanel extend JPanel?

Edited: I just looked at the code again. Disregard the above comment.

Edited: I just looked at the code again. Disregard the above comment.

'My name is Alice, but —'
'It's a stupid name enough!' Humpty Dumpty interrupted impatiently. 'What does it mean?'
'Must a name mean something?' Alice asked doubtfully.
'Of course it must,' Humpty Dumpty said with a short laugh: 'my name means the shape I am — and a good handsome shape it is, too. With a name like yours, you might be any shape, almost.'

...


'When I use a word,' Humpty Dumpty said, in rather a scornful tone, 'it means just what I choose it to mean — neither more nor less.'
'The question is,' said Alice, 'whether you can make words mean so many different things.'
'The question is,' said Humpty Dumpty, 'which is to be master — that's all.'

I am so sorry. That was stupid of me to just put something up here without tell you the error. well this is what i get

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
DummyPiece cannot be resolved to a type
DummyPiece cannot be resolved to a type

at .ChessPanel.<init>(ChessPanel.java:33)
at .ChessWindow.main(ChessWindow.java:25)

chesspanel line 33 is

DummyPiece dummy = new DummyPiece();

chesswindow line 25 is

ChessPanel j = new ChessPanel(frame);

[Fubarable]

Dumb question, I know, but do you have a DummyPiece class somewhere?

[sccot21]

yes i do would you like for me to upload it

[Fubarable]

yes i do would you like for me to upload it

Yes, that would be nice, if it's short. Is it in the same package as the classes you've posted above? If not, do you import it into the above classes?

[sccot21]

public class DummyPiece implements ChessPiece {


@Override
public boolean isWhite() {
return false;
}


@Override
public boolean isBlack() {
return false;
}


@Override
public void draw(Graphics g, Rectangle bounds) {
Color oldColor = g.getColor();

g.setColor(Color.red);
g.fillRect(bounds.x, bounds.y, bounds.width, bounds.height);

g.setColor(oldColor);
}


@Override
public ChessSquare getSquare() {
return null;
}


@Override
public void moveTo(ChessSquare square) {
}

}

I have it in the same package with everything else

Moderator edit: quote tags changed to code tags in the post above to help code retain formatting.

To the original poster: please read up on how to use [code] [/code] tags here.

[sccot21]

public class DummyPiece implements ChessPiece {

	
	@Override
	public boolean isWhite() {
		return false;
	}

	
	@Override
	public boolean isBlack() {
		return false;
	}

	
	@Override
	public void draw(Graphics g, Rectangle bounds) {
		Color oldColor = g.getColor();
		
		g.setColor(Color.red);
		g.fillRect(bounds.x, bounds.y, bounds.width, bounds.height);
		
		g.setColor(oldColor);
	}

	
	@Override

	}

	
	@Override
	public void moveTo(ChessSquare square) {		
	}

}

I can't fully explain your error if your DummyPiece class is present in the same package as the other classes and has been compiled correctly.

[sccot21]

ok thank you. I may just have to start over and try to see if i can do it again without it giving me errors.

[Fubarable]

Why did you edit the post of yours that I already corrected? You've changed the code tags that I placed back into inappropriate quote tags.

[Fubarable]

Is DummyPiece.java in its own file, or is it nested in another file?

[sccot21]

Why did you edit the post of yours that I already corrected? You've changed the code tags that I placed back into inappropriate quote tags.

I am sorry I thought you had wanted me to do it so i went back and re posted it

[sccot21]

its in its own file
