Average Three Numbers) You have just written an application that takes three numbers as input in JTextFields, stores the three numbers in variables and then finds the aver- age of the numbers. The output is displayed in an uneditable JTextField (see Fig. 5.35, which displays the incorrect output). You soon realize, however, that the number displayed in the Average is: JTextField is not the average, but rather a number that does not make sense given the input. Use the debugger to help locate and remove this error.
a) Copying the template to your working directory. Copy the C:Examples Tutorial05ExercisesAverageDebugging directory to your C:SimplyJava directory.
b) Opening the Command Prompt window and changing directories. Open the Command Prompt window by selecting Start > Programs > Accessories > Command Prompt. Change to your working directory by typing cd C:SimplyJavaAver- debugging.
c) Running the application. Run the Average Three Numbers application by typing java Average. Type 5, 7 and 11 in the three input JTextFields. View the output to observe that it is incorrect. The average of these three numbers should be 7 in integer arithmetic. (Recall from Section 5.5 that integer division yields an integer result.)
d) Compiling with the -g option. Compile your application for use in the debugger by typing javac -g Average.java.
e) Starting the debugger. Close the application and start the debugger by typing jdb.
