1) Typing quickly and correctly is an essential skill for working effectively with computers and the Internet. In this exercise you will build a GUI application that can help users learn to "touch type" (Le. type correctly without looking at the keyboard). The application should display a virtual keyboard and should allow the user to watch what he or she is typing on the screen without looking at the actual keyboard. Use JButtons to represent the keys. As the user presses each key, the application highlights the corresponding JButton on the GUI and adds the character to a JTexIArea that shows what the user has typed so far. (Hint: To highlight a JButton, use its SetBackground method to change its background colour. When the key is released, reset its original background| colour. You can obtain the JButton's original background colour with the getbackground| method before you change its colour.] yping Tutor Type some text using your keyboard. The keys you press will be highlighted and the text wi be displayed. Note: Clicking the buttons with your mouse will not perform any action. Backspace Tab R P Caps AsD " K Enter Shift

Running Time of Application

The application has a feature called running time. It is one of the parameters for measuring its performance. It is written in a particular language and is designed to perform a specific task. Applications run in a specific environment. The execution of the business will depend on the application’s running time. It must be optimized in order to get the maximum benefits out of the application.
