Alright I thought I had this coded properly for my homework assignment
but for some reason it does not work as I thought it would. Basically
what I have to do is create an applet that will display an employee
title if you enter in an employee name and an employee name if you
enter in an employee title. It works fine when you enter in a name
but only works if you enter in the first job description.

"Tyler Smith"};
String emptitles[] = {"Computer Technician", "Office Manager",
"Superman"};

jobtitledisplay.setText(result.getText());
break;
}
else if
(emptitles[i].equalsIgnoreCase(jobtitledisplay.getText())) {
result.setText(empnames[i]);

break;

hi
in this programme you are making mistake in line
for(int i = 0; i < empnames.length; ++i) {
in this line you should have run the for loop for i<= emnames.length
times that is
for(int i = 0; i <= empnames.length; ++i)
Hope you might get it.
i am writing your modified programme that work
