Explanation of the Code and Unit test Screen Shots:

I have used java language and eclipse software to implement GetCourseByCourseID method. In short my code takes user-input to select one of three available courses. After entering one of the course, the code calls GetCourseByCourseID method in which it checks the user-input course id from course[] Array. If course id matches then my code shows all details of the course otherwise it gives an error that “course does not match”.

Here are the steps given what my code does:

1. When you run code , this message will be seen on the console

2.Input course id.

2. Same as step 2, with different course id

3. Same as step 2, with different course id

4. If wrong course id is written
