inherittance

Develop a class Borrower which has 5 important fileds, namely borrowerId, borrowerName, borrowerLastName, contactNumber and dateOfBirth. Your class must demonstrate good encapsulation where all fileds get manipulated through get and set methods. Save your file as Borrower.java

Sample input

The borrower class is instantiated four times using the following sample data:

borrowerId[10420040, 10420041, 10420042, 10420043]

borrowerName[David, Mike, Steve, Finsen]

borrowerLastName[Desalt, Smith, Sugars, Lions]

contactNumber[7820001, 1209111,8912100,79910211]

dateOfBirth[1990-11-01, 1981-12-12, 1991-22-03, 1980-10-02]

The program should allow the system administrator to search for a certain borrower in the class by inputing the borrower's ID in the input screen & return the search results on a message dialog box.
