First create a text file with four lines.  The first should be your name, the second your social security number, then your e-mail address and finally your telephone number.  Save this on your disk.

Next write a Java applet to read this information into a class and then display it in text boxes.  Your program should have at least two classes.  The first one is the main class that extends the Applet class.  It should create TextFields and Labels for each of the data items in the file.  Then it should instantiate the second class and call methods in it.

The data in the second class should correspond with the data in the file.  It should have at least two methods, one to read the data into the class and the other to display the data in the text boxes on the applet.

Hand in a printout of your program together with a disk with the file and the .java, .class and .html files.  You can use the program below to guide you in writing your program.
