    Default Does MessagePanel class/ component exist in Java awt/ swing?

    Hello, there I am quite new to Java programming and am currently working on JApplet in Java. Just wondering that is there any MessagePanel class/component (something similar to JPanel class)in java awt/ swing because when I tried to instantiate this statement -->MessagePanel inputPanel=new MessagePanel(); inside my IDE. It seems that the compiler is underlining the MessagaPanel as an error. Greatly appreciate anyone who help to provide me some guidelines on this.

    MessagePanel is not a standard Java component. JPanel and JApplet both are.

    If you have a MessagePanel class, you're going to have to post an SSCCE that demonstrates what you're trying to do.

    import java.awt.*;
    import javax.swing.*;
    import java.awt.Font;
    import java.awt.BorderLayout;

    public class DisplayMessage extends JApplet {


    public void init(){
    String message=getParameter("inputMessage");
    int x=Integer.parseInt(getParameter("X"));
    int y=Integer.parseInt(getParameter("Y"));

    MessagePanel inputPanel=new MessagePanel();
    inputPanel.setXCoordinate(x);
    inputPanel.setYCoordinate(y);

    Container contentPane = getContentPane();
    contentPane.add(inputPanel);
    }
    }
    hello there, this is the code.

    Where have you seen the MessagePanel class? Did you look in the API doc for the Java SE classes?

    If you don't understand my answer, don't ignore it, ask a question.

    I got it from a reference book in which I am trying to learn Java from. Yeap, I looked for the messagePanel in the API doc, but it seems that I couldn't find it.

    Chances are MessagePanel is defined somewhere else in the book, or it's just an example. It's not a standard Java class.
