Develop an application that simulates rolling two six- sided dice. Your application should have a Roll JButton that, when clicked, displays two dice faces (images) corresponding to random numbers. It should also display the number of times each face has appeared. Your application should appear similar to Fig. 15.27. This application will help you see if dice rolling on your computer is really random. If it is, the number of 1s, 2s, 3s, 4s, 5s and 6s you roll should be about the same, at least for a large number of rolls.
a) Copying the template to your working directory. Copy the C:Examples Tutorial15ExercisesDiceSimulator directory to your C:SimplyJava direc- tory.
b) Opening the template file. Open the DiceSimulator.java file in your text editor.
c) Displaying the die image. After the rollJButtonActionPerformed method, in line
211, create a method named displayDie that takes a JLabel component as its argu- ment. This method should create a new random integer from 1 to 6 using the next- Int method of the Random object generator and assign that value to the variable face. Display the die image in the JLabel component that was passed as an argu- ment. The die image should correspond to the random number that was generated. To set the image, refer to the code presented in Fig. 15.25. Finally, this method should call the displayFrequency method to display the number of times each face has occurred.
d) Coding the rollJButtonActionPerformed method. Add code to th
