Answer 1

courseStudent.setName("Smith");

courseStudent.setAge(20);

courseStudent.setID(9999);

courseStudent.printAll();

System.out.print(", Id: " + courseStudent.getID());

This is the part of the code that needs to be added in order to print the output same as mentioned in the question. These lines should be added in the main method where solution is asked.
