Question

can someone help me modify my program?

1. Modify the program so that it asks the user for the person to look up:

Name? Violet Smith

The number is (312) 223-1937

Name? James Barclay

The number is (418) 665-1223

Name? Scott Eccles

Name not found

Name? quit

good-bye

2. Modify the PhoneEntry class so that it contains firstName, lastName, and phone#.

Last Name? Smith

First Name? Violet

The number is: (312) 223-1937

Last Name? Smith

First Name?

John Smith: (812) 339-4916

Violet Smith: (312) 223-1937

Willoughby Smith: (312) 992-8761

Last Name? quit

good-bye

3. Modify the program program so that it can deal with an array that has null in some cells. Now alter the program so that the user has a choice of 3 actions

-Search for a name

-Add a new name and ph num. to the array

-Delete a name (and ph num.) from the array

This is the program that I created now I just have to modify it.

         for (int j=0; j<phoneBook.length; j++)

         {

            if ( phoneBook[ j ].

            name.equals( targetName))
