I am tasked with the folllowing:
In Eclipse, implement your account class diagram created earlier. Complete the following:
Your Java project should include 3 classes:
Account.java, Services.java, and Supplies.java.
There should be implemented constructors for
each class.
The toString() method should be overridden to
provide a readable string representation of each object.
Getters and setters need to be implemented to
enforce data hiding.
The calculateSales() method should be
implemented for all classes
Consider having the
calculateSales() as an abstract method for the Abstract Account
class.
In addition, you need to create a test class
companySales.java that tests each subclass's constructor,
toString(), and computeSales().
You need to create an instance of each
subclass.
Input can be hard-coded or entered by the
user.
You need to call the method calculateSales() for
each instance.
You need to print each class info using its
method toString().
Code should be fully commented.
Program flow should be logical.
