In addition to the comments, RAD generates the following code:

package c3;

import java.awt.Frame;

public class EmpFrame extends Frame {

}

Notice that RAD included the correct import statement and placed the extends keyword in the header to define
EmpFrame as a subclass of Frame .
Congratulations; you have defined EmpFrame as a subclass of Frame . Of course, EmpFrame doesn't do anything,
but it will after we set the properties, and add some components and methods.

Tutorial: Defining and Adding a Label
We need to create a label (to display the employee name) and add it to EmpFrame. The following statements will do that:

A. Import the java.awt.Label class

B. Create a Label object and variable and assign the object to the variable

C. Define the label text

D. Define the label size

E. Define the label location

F. Add the label to the frame

1. Add the following import statement after the already existing import statement:

import java.awt.Label;
We will create a label and assign it to a class variable called empNameLbl.

2. Inside of the EmpFrame class, enter the following statement:

Label empNameLbl = new Label("My First Label");

This statement does three things:

A. Creates a Label object with the text “My First Label”

B. Creates a Label variable called empNameLbl

C. Assigns the object to the variable

3. Insert the following code after the label statement:

public EmpFrame(Employee emp) {
}
