Lab Quiz 1

Read all instructions before you begin. As always, you are expected to commit and push at LEAST after completing each Problem.

Resources Allowed

There are a limited number of resources allowed on this exam:

• Official Java Documentation (any page at docs.oracle.com).
  • You may use google to search for the official Java documentation, but may not click on any link that isn't to docs.oracle.com
• Your GitHub repositories from previous labs.
• Your online textbook.

Using any other resource to complete this quiz will be considered an academic integrity violation.

Grading

You should show a TA your work after completing each problem in order to get full credit. You must complete this lab within your lab period.

Problem 1 (5 points)

The Instructor class consists of a firstname (String), lastname (String), office building (String) and room number (int). There is a no-arg constructor that initializes the properties to “Albert”, “Einstein”, “McNair”, 420. There is also a constructor with a parameter for each class property. Finally, there is a toString() method that returns each property separated by an asterisk * .

1. Create a Netbeans project and name it CourseScheduler.
2. Implement the Instructor class in Java. Declare and instantiate two Instructor objects in the main() method of your project (one object using each constructor). Output the object properties to the console using the toString() method. When you are finished, get the TA to check your code to get the lab points.

Problem 2 (5 points)

The Textbook class consists of a title (String), publisher (String) and edition (int). There is a no-arg constructor that initializes Strings to “” and numeric values to zero. A second constructor has formal parameters for each property. The class toString() method returns a String with each property separated by a System.lineseparator() char.

1. Implement the Textbook class in the CourseScheduler project. Declare and instantiate Textbook objects in the main() using both constructors. Output the object properties using the toString() method. When you are finished, get the TA to check your code to get the lab points.

Problem 3 (5 points)

The Course class consists of a name (String), semester (String), instructor (Instructor) and textbook (Textbook). As with the previous classes, there are two constructors: one no-arg constructor and one constructor with formal parameters for each property. The no-arg constructor initializes reference variables to null. The toString() method separates the name and semester by a comma (‘,’). There is a System.getProperty(“line.separator”) char after the semester property and between the Instructor and Textbook properties. The Instructor and Textbook properties are formatted using the toString() method from their respective classes.

1. Implement the Course class in the CourseScheduler project. Instantiate Instructor and Textbook objects and use them along with the course name and semester as parameters to the Course constructor. Output the properties of the Course object using the toString() method. You can verify the format of the toString() by comparing it with the file input format described in Problem 4 below. When you are finished, get the TA to check your code to get the lab points.

Problem 4 (5 points)

1. Declare and instantiate an ArrayList in the main() method. Name it courses.
2. Implement the following method in the same class as the main(): public static void readCourseData( ArrayList courses, String filename )
3. Make a call to readCourseData() from the main() passing the ArrayList and the filename as parameters. Write a loop under the call to readCourseData to output all the course data to the console by calling toString() for each Course object in the ArrayList.
