NOTE: There are 3 exercises in this module introducing you to arrays in Java. The first 2 exercises require only 1 class for each. The third exercise requires 2 classes. Create asingle projectthat will includeall 4 class files: Quizzes.java, ReverseArray.java, NameAndZip.java, and NameAndZipList.java
Submit the following:
An exported NetBeans project named "YourLastNameModule8Lab” containing all 4 classes.
Run each project and paste your test run output to the bottom of your Client file and then comment out that output.
