Complete the code for the class Student by writing the required methods. The instance variables are as given in the incomplete code shown below. The requirements are stated under the code below.

Requirements for the method findCreditsRemaining : This method returns the number of credits remaining for the student .Use maximum number of credits required as 120. This method uses the instance variable, creditsEarned to find creditsRemaining = 120-creditsEarned. The method returns the value of creditsRemaining. Please make sure the method definition has proper return type. This method has no parameter.

Requirements for the method findStudentStatus: This method returns the value of students status as one of the following values: freshman, sophomore, junior , or senior. The logic to determine the student status is as follows: If the students earns more than 90 credits, the status is senior, else if the student earns more than 60 , but less than 90 the status is junior, else if the student earns 30 or more but less than 60, the status is sophomore, else for credits less than 30 the status is freshman. You may declare a return variable called status, update this variable using the logic written above and return the value of this variable.

Write a class called StudentAccount. This class has two instance variables called accountBalance,which is of the data type double, and studentAccountID of type String. In addition, there are three methods, whose requirements are given below.

1. Method called getAccountBalance, which is a getter for the instance variable accountBalance.
2. Method called addTuitionBalance that has a void return type and takes in a parameter called credits, of the type int. The parameter credits is the number of new credits that a student enrolls in. The addTuitionBalance method updates the accountBalance by adding the value of credits* 322.0 to the existing accountBalance. Here 322.0 is the price of one credit.
3. Method called makeTuitionPayment that has a void return and takes in a parameter called amount, of the type double. This method updates the accountBalance by subtracting the amount paid.

3. Create a class called Student that represent some basic enrollment information about the student. The instance variables are studentID , creditsEarned and gpa, which are String, integer and double, respectively .( you may either create a new class, or add extra features to the class that you have in problem 1).

Define constructors in the Student class that can do the following in any client class:

• Create a new Student object using the default constructor. Pick any default values of your choice, for the default constructors instance variables.
• Create a new Student object using overloaded constructor that takes in three arguments that provide values for the three instance variables.
• Create a new Student object using a 2 argument constructor .The two arguments will provide values for studentID and creditsEarned instance variables.

4. Continuing along problem 3), create a client class called TestStudent in which you will write statements that will create 3 objects using each of the constructors specified in the Student class. You may call the objects student1, student2 and student3. You may choose any appropriate argument values for the overloaded constructors.
