Constructor Detail

Project

public Project(int linesOfCode,
               int deadline,
               int maxEmployees)
        throws java.io.FileNotFoundException

Creates a new instance of a Project. This is constructor chaining. It calls the other constructor with a new Random number each time.

Parameters:

linesOfCode - lines of code needed for the project

deadline - how many days assigned to complete the project

maxEmployees - the maximum amount of employees you can assign to a project

Throws:

java.io.FileNotFoundException - exception thrown if file is not found

Project

public Project(int linesOfCode,
               int deadline,
               int maxEmployees,
               long seed)
        throws java.io.FileNotFoundException

Parameters:

linesOfCode - lines of code needed for the project

deadline - how many days assigned to complete the project

maxEmployees - the maximum amount of employees you can assign to a project

seed - allows us to have reproducible results

Throws:

java.io.FileNotFoundException - exception thrown if file is not found

Method Detail

linesNeededPerDay

public int linesNeededPerDay()

Helps assigns programmers and testers to the project.

Returns:

Lines of code needed per day

completeProject

public void completeProject()

Each day, so long as the project is not complete (while there are still lines of code to write or test)

1. add one day to the daysWorkedSoFar of the project (hint: check out the instance variables)
2. call each employee's work method. If the employee is a Programmer, add the result of the work method into the variable you created to count the number of lines coded. Else if the employee is a tester add the result of the work method into a variable for lines tested.

hint: You will want to create local variables to keep track of the lines of code that have been written and tested. You will want to compare these local variables to the instance variable, linesOfCode.

If you finish the recitation early: Change your code to ensure that the testers never test more code than the programmers have coded. I have made this problem easier by adding the programmers to the ArrayList first.

toString

public java.lang.String toString()

A string representation of a particular project. The String should consist of the following:

1. "Deadline: " + deadline, followed by a newline
2. "Days required: " + daysWorkedSoFar, followed by a newline
3. "Employees on Project:", followed by a newline
4. Each employee's (toString) separated by a newline

Adding each employee to the string that you will return can be done in one of two ways:

• Loop through employeesOnProject array and add the employee's toString with a newline character
• Use the String.join method (Java 8) with the following arguments: a newline character and employeesOnProject.stream().map(Object::toString).collect(Collectors.toList())) this creates a list of Strings using the Employee toString method. It's a little bit messy, but it gets the job done.

WARNING: DO NOT PRINT IN THIS METHOD. The toString should only return the string representation of the class.

Example:

Deadline: 15
Days required: 16
Employees on Project:
Programmer Carla Landon, average productivity: 140 lines
Programmer Carisa Belvin, average productivity: 131 lines
Programmer Laura Mccarty, average productivity: 113 lines
Tester Melisa Bucholz, average productivity: 80 lines
Tester Bernetta Reber, average productivity: 85 lines
Tester Tanisha Mckoy, average productivity: 81 lines
Tester Lorrie Coller, average productivity: 88 lines

Overrides:

toString in class java.lang.Object

Returns:

the string representation of a project

main

public static void main(java.lang.String[] args)
                 throws java.io.FileNotFoundException

Throws:

java.io.FileNotFoundException
