#10. Are the two definitions of the constructors for the class Student (Segment C.2) an example of overloading or overriding? Why?

#11. If you add the method setStudent( Name, String ) to the class CollegeStudent and let it give some default values to the fields year and degree, are you overloading or overriding setStudent() in the class Student? Why?

• Write a program to use the two constructors of Student. One Student is default and the second is you (Name and student id). Write comments (not JavaDoc) in your code to answer #10.
• Continue your program with a default CollegeStudent and then using the added method setStudent( Name, String ) in CollegeStudent and me, new Name( "Mr.", "Reed" ), "000-01". Write comments in your code to answer #11. Note you have to write code for the added method setStudent().
• Attach your program and CollegeStudent.java.
