Description: Unit 9 - Java Arrays and Data Files

This unit is really about three different topics that are related to one another – arrays in Java, simple text files in Java, and modular programing in java (Java methods).

The unit has a programming project spread over three related programming assignments, each worth 10 points.

In the first assignment, you will create a Java program that works with a small array of data containing five test scores. It will get data from user input do some calculations, and then print the results.

In the second assignment, you will modify a copy of the first assignment to load the data from a data file into an array, and then output the results to a data file.

In the third assignment, you will decompose a copy of the second assignment into separate methods in Java.

Our goal is to have a good modular program that loads stored data from a fie into an array, works with the data, then sends results to another data file. Doing this in three parts will allow you to focus on one aspect of the problem at a time.

There are reading assignments in Zybooks, but the two chapters from the Java Learning Kit – Chapter 5 – and Chapter 6 are your best source for learning this material. They cover the things you need to learn to complete this project and have good sample programs.

Your tasks are to:

Read Zybooks Assginment 11 - Arrays in Java.

Read the material in JLK Chapter 6 about arrays in Java.

Complete the Java Arrays Programming assignment.

Read the material in Chapter 6 about text files in Java.

There is no corresponding Zybooks assignment.

Complete the Java Text Files Programming assignment.

Read the Zybooks Assignment 12 - Methods in Java

Read the material in JLK Chapter 5 about methods in Java.

Complete the Java Methods programming assignment.

It may seem like their is a lot to do here but the assignments are each simple and build on one another.
