Step 1 Getting Started Load your previous Studentjava file f

Step 1: Getting Started: Load your previous Student.java file from your previous Lab7 java. If you do not have th Student class or did not complete Lab 7, you can download the Lab 7 solution from the Blackboard a d use the Student class provided therein as your starting point. Step 2: Add Setter methods and remove the constructor Inside the class, we have declared some data members: an integer variable called student/D, a String variable called studentMajor, a String variable firstName, a String variable lastName, an int called studentCredits, and an int called studentPoints You need to supply the following setter methods: setid(int id) to set the ID of the Student object. setMajor(String major) to set the major of the Student object setGradepoints (int points) to set the number of points of the Student object setCredits(int credits) to set the total credits of the Student object setLastName(String IName) to set the last name of the Student setFirstName(String fName) to set the first name of the student . Remember to make these setter methods void. These methods do not return any value. Hint: public void setiD(int id) These method contains a line of code that returns the desired variable value(id, major...). II write a line of code sets the id to the student\'s id public void setMajor(String major)

Solution
