Assume that a class exists called 'Student' with the following fields: int mylD, double myGPA, and String myName. The student class has a constructor that takes values for all 3 fields (in the order shown above). The Student class also has setters and getters for each field. Determine the output of the following code:

![Assume that a class exists called 'Student' with the following fields: int mylD, double myGPA, and
String myName. The student class has a constructor that takes values for all 3 fields (in the order
shown above). The Student class also has setters and getters for each field. Determine the output of
