    Default GUI Java Help Please!

    Hello All ---

    I am working on the following assignment and need a little bit of help with my code.

    Write a program that has three buttons, each displaying a different text that when pressed will display the text on the button in a text box. (For an extra challenge, have the user choose the color of the displayed text as well).

    This is my code so far.

    import java.awt.*;
    import java.awt.event.ActionListener;
    import java.awt.event.*;
    class button extends Frame
    {
    button()
    {
    TextField objTextf;
    setTitle("press the button");
    setSize(300,300);
    show();
    }
    public static void main(String[] args)
    {

    Frame objFrame;
    Button objbutton1;
    Button objbutton2;
    Button objbutton3;
    objFrame = new button();
    objbutton1 = new Button("hello");
    objbutton2 = new Button("Hola");
    objbutton3 = new Button("Guten Tag");
    objTextf = new TextField("trial");
    objbutton1.setBounds(180,150,80,50);
    objbutton2.setBounds(100,150,80,50);
    objbutton3.setBounds(20,150,80,50);
    objFrame.add(objbutton1);
    objFrame.add(objbutton2);
    objFrame.add(objbutton3);
    objFrame.add(objTextf);
    objbutton1.addActionListener(new button1Listener());
    objbutton2.addActionListener(new button2Listener());
    objbutton3.addActionListener(new button3Listener());
    }
    public class button1Listener
    {
    public void buttonpushed(ButtonEvent me)
    {
    String S = objTextf.getText();
    objTextf.setText(S);
    }
    }
    }



    I am getting the error message --- cannot find symbol - class ButtonEvent ---

    The following line is highlighted -- public void buttonpushed(ButtonEvent me)

    Any help and advice is greatly appreciated! Thank you!

    The error message states it cannot find the class ButtonEvent. It is not part of the Java API, is it a class you have written yourself? If so where is it?

    Also, your button1Listener (etc) classes are not ActionListeners therefore cannot be added to your buttons.
