Applet Review

Make both programs. You have Wednesday, Thursday and Friday to complete it.

(1) Background Colour Selector

Make an applet that allows you to select the R, G, B values of the background (this can be done using a dialog box OR a JTextField). After a button is pressed, the background should change to the specified colours. There should be a title and it should be user friendly.

Extra Levels:

• Make the applet error test: the R, G, B values need to be between 0 and 255.
• Use a JSlider widget to make the R, G, B values.

To parse a number from the String x.

int n = Integer.parseInt(x);

(2) Days Alive

Make an applet that gets the date of your birth and today's date. Calculate the number of days that you have been alive and output it to the user.

Extra Levels:

• Auto generate today's date.
• Check for leap years.
• Error test: Year within a range (eg. no one ought to have been born before 1900 or after 2009), Month 1-12, Day 1-31 (or more complex).
• Get the date in the format dd/mm/yyyy. Note that the user can enter one digit for the month or for the day.
