(Arithmetic Calculator Application) Write an application that allows users to enter two numbers that can then be added or multiplied (Fig. 9.25). Users should enter each num- ber in an input dialog, displayed when the Enter Operands JButton is clicked. Each number should be appended to the Operands: JTextArea. The Add and Multiply JButtons are ini- tially disabled, but they should be enabled after the two operands are input. Once a result is calculated using the Add JButton, this JButton should be disabled until two new numbers are added. Once a result is calculated using the Multiply JButton, this JButton should be disabled until two new numbers are added.
a) Copying the template to your working directory. Copy the directory C:Examples Tutorial09ExercisesArithmeticCalculator to your C:SimplyJava directory.
b) Opening the template file. Open the ArithmeticCalculator.java file in your text editor. Lines 25–26 in the template already declare two instance variables of type double—value1 and value2—that you will need in this application. Variable value1 will store the first value entered by the user, and value2 will store the second value entered by the user. Each variable is initialized to 0.
