(Calculator GUI) Many components have the same kinds of properties as JLabels. For instance, JButtons also have size, location and text properties. In this exercise, you will cus- tomize the plus (+) JButton in the Calculator GUI shown in Fig. 2.35.


a) Copying the template to your working directory. Copy the C:Examples Tutorial02ExercisesCalculator directory to your C:SimplyJava directory.
b) Opening the Command Prompt window and changing directories. Open the Command Prompt by selecting Start > Programs > Accessories > Command Prompt. Change to your working directory by typing cd C:SimplyJavaCalculator, then pressing Enter.
c) Compiling the template application. Compile your application by typing the command javac Calculator.java, then pressing Enter.
d) Running the template application. Run the application by typing java Calculator.
The GUI of the Calculator template application should appear as shown in Fig. 2.36. Notice that the plus (+) JButton is missing. The template application creates the plus (+) JButton, but the JButton’s default width and height are both zero, so it does not appear on the screen. You will customize the plus (+) JButton’s text and bounds properties to make it appear as in Fig. 2.35.
