Purpose

Purpose is to practice using file input and output, and array list of objects. Also, this

document tells you only what to do, you now have more responsibility to design how to

do it.

 

Problem description

You are given a text file called 'Students.txt' that contains information on many

students. Your program reads the file, creating many Student objects, all of which will

be stored into an array list of Student objects, in the Students class. The Tester class

controls everything, calling many Students class methods to produce lots of different

outputs. The program must write the output to an output file and to the Terminal

Window.

 

File and class specifications

Students.txt file format

Information for each student is stored in the file as 3 lines of text:

name

age

GPA

e.g. the following shows data for two students:

Name0

22

1.2

Name1

22

2.71

 

Student class

The Student class has instance variables and methods to represent one single student.

 

Your Student class must have exactly and only the following instance variables:

private String name;

private int age;
