// Registration

// This program creates student objects and call methods

// 1. instantiate the Students class – Create a student object

Students stud1 = new Students();

// 6. Create a batch of students using array

// 2. Set the student name

System.out.print(“Enter your first name: “);

String fName = input.next();

System.out.print(“Enter your last name: “);

String lName = input.next();

stud1.setName(fName, lName);

// 4. credit earned

stud1.setCredit(input.nextInt());

// int crt = input.nextInt()

// 3. class year

stud1.setClassYear();

// Display student greeting message

stud1.displayMessage();

// 5. Status checking with get methods.

Sytem.out.printf(“Hello %s,nYou will need to take %d credit hours to graduate in %d. n”,

// 7. Test on more students

// 8. Search for students

// HW9

//1. Create an object from the CreSecs class

//2. Stud will check course available – cal course display method.

//3. Take user inout if the decide to enroll into this course

//4. Call course availability check

//5. call student semester crdit check (We’d done together)

//6. Display the course record
