Answer to Question #309698 in Java | JSP | JSF for Sowmya

Question

Create a class named as Customerunder package :package2, which contains following private variables/ attributes,

Member Field name

Type

id

Long

name

String

gender

Character (M/F)

email

String

contact Number

String

Mark all the attributes as private

Add a default constructor and a parameterized constructor to take in all attributes.

Create a separate class Main under package :package2, within it's main() method, make 2 Customer objects and then compare between these Customers.

Two members are considered same if they have same email and contactNumber. Implement the logic in the appropriate function. (override equals method in class Customer)

Sample Input:

Customer1:

ld: 45

Name: John

Gender: M

Email: [e-mail] contact number: +997-4854-7485965123

Customer2:

ld: 12

Name: Marc

Gender: M

Email: [e-mail]

Contact number: +997-4854-7485965123

Sample Output:

Customer 1 and Customer 2 are different
