Lab 1b (Section E): the MobilePhone class

Create a MobilePhone class that stores load left (as a double) in pesos, total minutes called (as an int), and rate (as a double) in pesos per minute. Load and minutes consumed start at 0, rate starts at 6.50 pesos/minute.

Support the following methods:

public void load( double pesos )
public void call( int minutes )
public double getLoadLeft()
public int getTotalMinutesCalled()

optional:

public void changeRate( double newCallRate )
public void sendTextMessage(): subtract 1 peso from load
public int getNumTextMessages(): you will need an extra field to support this

Write this program in BlueJ and test the class by creating objects and running methods on that object. Also, write a MobileTester class that creates two MobilePhone objects and executes all the methods that you have implemented.

You will be given more than 1 hour to complete this lab. You are also expected to provide the proper documentation and comments within your programs.

Zip your BlueJ project and submit through moodle .
