I will explain to you how this program working. First, i build this program for mobile application actually in java. Mmmm, So this is a simple program, and when this program running it will display two main menu which you can choice, that is HelloMidlet and Task01 for this situation i recommended you to choice Task01. When you have choice it, you will go to the next display and you will able to select two choice between exit and why, i recommended you choice why. And next you will see alert message.
