Question

Java is an object-oriented programming language that enables us to define classes and to instantiate them into objects. These objects then call each other’s methods to implement the behavior of the application. The Unified Modeling Language (UML) is an object-oriented visual notation to document the design of object-oriented classes.

For this discussion, you will practice designing a Java class called Course, drawing a UML class diagram for the Course class, and then implementing the Course class in Java code. Review the Resources section to help you with this discussion.

Design a Java class called Course that has the following attributes:

1. code – a string field to store the course code (for example, IT1006).
2. creditHours – an int field to store the credit hours of the course (for example, 6).

Using one of the UML drawing tools available in the Resources, draw a UML class diagram for the Course class. Then implement your design of the Course class in Java.

You will be expected to provide a screenshot of the result of your work.

PLEASE COMMENT THROUGHOUT CODE AND EXPLAIN WHY YOU USED WHAT YOU USED. ALSO EXPLAIN HOW YOU DREW THE UML

Answer 1

There is a total of three images which contain an explanation.

This is the code which will create the class Course and the attributes.

// Save the file by name Main.java
// Defining class Course having two attributes
class Course
{
String code; // code attribute, which will store code
int creditHours; // creditHours, which will store credit hours
}

class Main // Main class
{
public static void main(String args[])
{
Course myCource = new Course(); // Creating a new object of class Course
myCource.code = "IT1006"; // Assigning value to code
myCource.creditHours = 6; // Assigning value to credit hours

System.out.println("Code : " + myCource.code ); // printing the code
System.out.println("Credit Hours : " + myCource.creditHours ); // printing the credit hours

}
}
