Class Employee

java.lang.Object

Employee

Direct Known Subclasses:

Programmer, Tester

public abstract class Employee
extends java.lang.Object

The Employee class contains functionality common to types of employees in the company. For example, all employees have a first name and a last name and an average number of lines of code that can be coded or tested. On a side note, a few reminders pulled straight from the Oracle documentation
An abstract class is a class that is incomplete, or to be considered incomplete.
Normal classes may have abstract methods (methods that are declared but not yet implemented) only if they are abstract classes.

Constructor Detail

Employee

public Employee(java.lang.String firstName,
                java.lang.String lastName,
                int averageLinesOfCode)

Remember, objects from the abstract class cannot be instantiated. When an abstract class has a constructor it is used to initialize values that are available to all concrete classes.

1. assign values to each instance variable
2. call the setRandom method (should be last line of code).

The setRandom method establishes a particular and unique seed for each employee.

Parameters:

firstName - the first name of the employee

lastName - the last name of the employee

averageLinesOfCode - lines of code the employee can program or test

Method Detail

getFirstName

public java.lang.String getFirstName()

Returns the first name of the employee.

Returns:

The first name of the employee

getLastName

public java.lang.String getLastName()

Returns the last name of the employee.

Returns:

The last name of the employee

getAverageLinesOfCode

public int getAverageLinesOfCode()

Returns the average number of lines of code an employee can write or test.

Returns:

the average number of lines of code.

toString

public java.lang.String toString()

A string representation of an employee. The string should consist of the following (also see the examples below):

1. "Programmer" if the Employee is a programmer, "Tester" otherwise followed by a space
2. The first name followed by a space
3. The last name followed by a comma and a space
4. The string "average productivity: " + averageLinesOfCode + " lines".
5. Do not end with a newline character.

WARNING: REMEMBER TO NEVER PRINT in the toString. This should just be returning the string representation.
HINT: You can use either instanceof to differentiate or this.getClass().getName() to get the class. Is one better than the other? Is there a better way to do this?

Examples:
Programmer Dani Durand, average productivity: 101 lines
Tester Fransisca Ettinger, average productivity: 80 lines

Overrides:

toString in class java.lang.Object

Returns:

the string representation of a single employee

work

public abstract int work()

The amount of work an employee does each day. Implemented in the concrete classes.

randomBetween

public int randomBetween(double lower,
                         double upper)

A helper method to return a random whole number inclusively between two bounds. Created to to be used in the Programmer and Tester work methods.

Parameters:

lower - lower limit

upper - upper limit

Returns:

a random integer between the lower and upper limit.
