Two types of persons need to makeрayment:- Class LoanLender describes a loan. For a loan, we have a maximum limit for example 100K, andan interest rate, for example 7%- Class SIMUOW describes a student who needs to pay school fees depending on the number ofareas of focus. Students can take at most two areas of focus. For example, per area of focus cost is5K per term, and project's cost is 10K. The University gives 5% discount to students who registerto two areas of focus. Student who has project can only have one area of focus.We now list down the classes that you need to design for this question: Note that all classesdesigned by you must be complete classes; for example, other constructors including the copyconstructor, accessor and mutator methods, toString method must be inside the classes.(1) The interface class called Payment. In this class, you should declare all the constants listedabove in it and use them in your design. The interface class has an abstract method calledgetPayment. Its prototype is specified aspublic double getPayment ();(2) Usefullnfo class is an abstract class which implements the interface Payment. In this class,you have two final instance variables, name and gender. An exception is thrown if the gender isinvalid. Usual info for classes should be defined inside the class. The toString method returns astring with specified format (refer to the sample printing examples in this question, basically isone instance variable per line).(3) LoanLender class is a concrete subclass of Usefullnfo class. A LoanLender object has a name,a gender, an identity number, takıng a loan of certain amount and intends to use a few years topay by installments, i.e. override the getPayment method. The formula uses to compute theinstallment per month isTotal interest = loan amount * rate * yearInstallment per month = (loan amount + total interest) / (year *12)Note that you should make sure that the loan amount is in range and the number of years to payfor installments must be at least one year; otherwise throw relevant exceptions. Refer to the sampleoutput for toString method.(4) SIMUOW class is a concrete subclass of Usefullnfo class. A student of SIMUOW has a name,a gender, a student id (you can make use of a static variable to initialize the student id, forexample, starting from 2020000). SIMUOW objects derived from this class take no area of focus(You should know what to put in the getPayment method). Refer to the sample output fortoString method.(5) SIMUOW_1 class is a subclass of SIMUOW class. SIMUOW_1 object has a name, a gender, astudent id and has one area of focus (enum type, see UML diagram). Override the getPaymentmethod. Refer to the sample output for toString method.(6) SIMUOW 2 class is a subclass of SIMUOW 1 class. SIMUOW 2 object has a name, a gender,
