PhoneBook system using Map Collection

// The small previous project of phonebook system but by using Map collection as storage in which a user can add, update, delete and search records. Here, the records are not stored permanently. You will have to add new records afresh each time you run the program.

The default tab of the program

Adding Records in PhoneBook 

Searching and Editing the existing record

Need to click on SAVE to save the updated record

Deleting some record from the PhoneBook

Validation applied in different Textfields(as shown for Email)
