    Please ask as specific a question as possible. Right now it's hard to know what you need to do, or more importantly exactly where your stuck. Also show what you've tried and explain how it's not working.

    I'm not even sure how to go about doing a graphic... I tried to follow my professors examples, but I cannot get anything to work.
    He gave us an example of a rectangle :/ and i cannot even get it to compile correctly.

    --- Update ---

    For my assignment, this picture is all he gave us.

    I will take a look at this, thank you!

    --- Update ---

    I try to follow the tutorial.
    package painting;
    import javax.swing.SwingUtilities;
    import javax.swing.JFrame;

    public class Bus {
    public static void main(String[]args){
    SwingUtilities.invokeLater(new Runnable(){
    public void run(){
    createAndShowGUI();
    }
    });
    }
    private static void createAndShowGUI(){
    System.out.println("Create GUI on EDT"+
    SwingUtilities.isEventDispatchThread());
    JFrame f=new JFrame("Swing Paint Demo");
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setSize(250,250);
    f.setVisible(true);
    }
    }
    i typed this in notepad...
    but i get the compiler error of
    C:\Users\aml46720\Documents\bus.java:5: class Bus is public, should be declared in a file named Bus.java
    public class Bus {
    ^
    1 error

    should be declared in a file named Bus.java
    A public class must be in a file with a name the same as the class name.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
