    Default Noob Question

    import javax.swing.*;
    import java.awt.*;
    import java.awt.event.*;

    public class MyCard
    { private boolean treeLit = False;
    private JButton treeLitButton = new JButton("Turn Lights On");
    private JButton treeNotLitButton = new JButton("Turn Lights Off");


    public MyCard()
    { setTitle("Hello there");


    Can anyone tell me why 'False' and 'NewTitle' are showing as an error?

    showing as an error?
    When getting errors, please copy the full text of the error messages and post it.

    Java is case sensitive. Check the spelling.

    java: cannot find symbol
    symbol: variable False
    location: class MyCard

    java: cannot find symbol
    symbol: method setTitle(java.lang.String)
    location: class MyCard

    --- Update ---

    I have fixed the 'False' error, just the 'setTitle' one to fix now.

    The compiler gives the cannot find symbol error message when it can not find a definition for the symbol given in the error message.

    Where is the variable: False defined?
    Where is the method: setTitle defined in the MyCard class?
    The compiler can not find their definitions.
    If you don't understand my answer, don't ignore it, ask a question.
