Task

For this lab you will fix theQuiz.javaprogram. It tries to read in a list of quiz scores, drop the lowest score, and then return the average of the remaining grades.

It uses a file calledscores.txtwhich you can download and test with. The test file doesnt have any problems and you can assume it will be there when the program runs.

The program itself, however, has a couple of compiler errors, as well as some run-time logic errors in it. Some of these run-time problems will be exceptions that crash the program and one is a logic error that results in the wrong output. Your job is to fix these problems and get the code working.

When you are done, the example file should give the following output: --------------------- $ java Quiz Average is 4.5 --------------------- Contents of Quiz.java:
