Lab07
- Exercise 7.13 Write an applet that inputs 5 numbers, each
of which is between 10 and 100, inclusive. As each number is
read, display it only if it is not a duplicate of a number
already read. Use the GUI techniques introduced in Chapter 6.
Display the results in a JTextArea.
Use JTextArea method setText to update the results after
each value is input by the user.
- classname: UniqueFinderApplet
- Hint: See the MultipleApplet.java example
on the Week 6 web page for an example of how to build a GUI.
- Exercise 7.15 Write an applet to simulate the rolling of
two dice. The sum of the two values should then be calculated.
Your program should roll the dice 36,000 times. Use an array to
tally the number of times each possible sum appears. Display the
results in a JTextArea in tabular
format. The applet should use the GUI techniques introduced in
Chapter 6. Provide a JButton to
allow the user to reset the counts to zero and then roll the dice
another 36,000 times.
- classname: DiceRollerApplet
