in java, Write a class that represents a student. Every student has a name, an id number, a number of credits, and a number of grade points. Also, include in your class a default constructor, a second constructor with all parameters, an accessor method (getter) for the student name, and a method called gpa that will calculate and return the student’s grade point average. (Hint: gpa = points/credits)   Using the class that you just wrote, answer the following questions. Write code that will declare and initialize an object using the default constructor. Write code that will declare and initialize an object using the overloaded constructor. Write code that will retrieve and print the student’s gpa from #2.
