Question

JAVA Language

Write an Undergraduate subclass of student. Each Undergraduate has a major, degree (like BS or BA), number of credits earned, tuition balance, and gpa, in addition to name id, and phone as in the super class. Include constructors, get(), set(), pay(), toString(), and status() methods. the pa() method should accept an amount as parameter, print the current balance, update tuition balance by subtracting the amount from the current balance and print the new balance (for example pat (500) should decrease the current balance by 500 to get the new balance). the status() method should print" Congratulations! you are admitted into Honors List" if the gpa>=3.7, "your gpa is "+gpa+". you could raise it to 3.7 and be on Honors List " if gpa>=3.0 but 3.7 " your gpa is "+gpa+ try hard to raise your gpa " if gpa>=2 but <3.0, and fanally " you GPA has fallen below 2.0! you are on probation" if gpa<2.0 00 .

        this.phone = phone;
    }
    //Default Constructor
    public Student()
    {
        id ="";
        name ="";
        phone ="";
