Write a class called Course_xxx that represents a course taken at a school. Represent each student using the Student class from the Chapter 7 source files, Student.java. Use an ArrayList in the Course to store the students taking that course. The constructor of the Course class should accept only the name of the course. Provide a method called addStudent that accepts one Student parameter. Provide a method called roll that prints all students in the course. Create a driver class...

Generics Suppose you need to process the following information regarding Students and Courses: A Student has a name, age, ID, and courseList. The class should have a constructor with inputs for setting name, ID and age. The class should have setters and getters for attributes name, ID and age, and a method addCourse, removeCourse, printSchedule. courseList: use the generic class ArrayList<E> as the type of this attribute addCourse: this method takes as...

Language Java Step 1: Design a class called Student. The Student class should contain the following data: firstName lastName studentID totalCredits gpa Your class should implement the “sets” and “gets” for the class. Include methods: equals, compareTo, toString. Change the toString method (from class) to put each member variable on a new line. Step 2: Write a driver program to test that Student works correctly. Test is with 3 students as given in class. Step 3: Write a “registration” program...
