Given this class, please add the requested methods in the designated spaces provided. Instance methods: a) Write two constructors that will initialize the instance variables for a Student instance as follows: 1) Write a constructor that takes in three parameters – an int, a String, and a double. The constructor will assign them to the ID, name, and GPA instance variables respectively. 2) Write a no-argument (zero-parameter) constructor that will set the ID to - 1, the name to “No name assigned”, and the GPA to –1.0. b) Write an accessor method for the name variable. c) Write a mutator method for the GPA variable. d) Write a toString() method that will display all three instance variables on a single line, with a | (vertical bar) character between each one. e) Write an equals() method that returns true only if all three instance variables are equal. public class Student { // declare instance variables here private int ID; private String name; private double GPA;
