Code the StudentAccount class according to the class diagramMethods explanation:pay(double): doubleThis method is called when a student pays an amount towards outstanding fees. The balance isreduced by the amount received. The updated balance is returned by the method.addFees(double): doubleThis method is called to increase the balance by the amount received as a parameter. The updatedbalance is returned by the method.refund(): voidThis method is called when any monies owned to the student is paid out. This method can onlyrefund a student if the balance is negative. It displays the amount to be refunded and set thebalance to zero. (Use Math.abs(double) in your output message). If there is no refund, display anappropriate message.Test your StudentAccount class by creating objects and calling the methods addFees(), pay() andrefund(). Use toString() to display the object’s data after each method called
Create an Account class that a bank might use to represent customers’ bank accounts. Include a data member to represent the account balance. Provide a constructor that receives an initial balance and uses it to initialize the data member. The constructor should validate the initial balance to ensure that it is greater than or equal to 0. If not, set the balance to 0. Provide three member functions:- credit($amount) should add amount to the current balance- debit($amount) should ensure that amount does not exceed the current balance and then reduce the current balance by amount. The balance should not change if amount exceeds the balance.- getBalance() should return the current balanceNote: Create a set of test data and then write a program to test the class.
