Write the KeanStudent class. The UML diagram of the class is represented below: KeanStudent - fullName: String - keanID: int -keanEmailAddress: String cellPhoneNumber: String + numberOfStudent: int + KeanStudent() + KeanStudent(fullName: String, keanID: int, keanEmailAddress: String, cellPhoneNumber: String) +getFullName(): String +setFullName(newFullName: String): void +getKeanIDO): int +getKeanEmailAddress(): String +getCellPhoneNumber(): String + setCellPhoneNumber(newCellPhoneNumber: String): void +toString(): String 1. Implement the KeanStudent class strictly according to its UML one-to-one (do not include anything extra, do not miss any data fields or methods) 2. Implement a StudentTest class to test the class KeanStudent you just created. • Create two KeanStudent objects using a no-args constructor and one from the constructor with all fields. o Print the contents of both objects. 。 Print numberOfStudent. 3. Add comments to your program (mark where data fields, constructors,…

MGMT SS STATS, an umbrella body that facilitates and serves various Social SecurityOrganizations/Departments within the Caribbean territories, stoodpoised to meet the needs of its stakeholders by launching an onlinedatabase at www.SSDCI.gov.
