I have a written code on a simple address book which allows addnew,view single entry and view all names. I have added the delete functionality to allow one to enter name to delete its entry but I get Error:

cannot find symbol
return addressBookEntry.delete();
symbol:method delete()
location:variable addressBookEntry of type AddressBookEntry
1 error

I am using a windows console to run it. Kindly check out my code below for the delete.

(Pay particular attention at the AddressBookDelegateImpl class in the public AddressBookEntry deleteAddressBookEntry( String name )
throws AddressBookDelegateException { method)

the problem is, you don't have a method called 'delete' without parameters. that's why it can't find it.

So I need to introduce a delete method?Where do I place it and how?Considering that the user has input the name variable which holds the addressbookEntry.Will it just delete that or with the entry details?Its quite confusing I thought return addressBookEntry.delete() would just do to delete the entry because its been introduced by import.java.io.File; .How should this be?

either that, or you have to replace delete() by the name and signature of the method you do have.

My DeleteActionArgument is:

package com.jjpeople.addressbook.actionargument;

import com.jjpeople.addressbook.action.ActionConstants;
import com.jjpeople.serviceworker.action.actionargument.AbstractActionArgument;

/**
 * This application uses a Service to Worker pattern which is located in the
 * package: com.jjpeople.serviceworker
 * <p>
 * Before calling the execute method on the ShowAddressAction, the controller,
 * AbstractController sets this class in the action. This class encapsulates
 * the arguments required to run the processing in the execute method of the
 * ShowAddressAction.

public class DeleteAddressActionArgument extends AbstractActionArgument
    implements ActionConstants {

    private String name;


    /**
     * Constructor
     *
     * @param name of the person we want to retrieve the address details
     * for
     */
    public DeleteAddressActionArgument( String name ) {

        super();
        this.name = name;
        setActionCommand( DELETE_ADDRESS_ACTION );
    }


    /**
     * Gets the name of the person we want to delete the address details
     * for

     * @return the name of the person we want to delete the address details

     */
    public String getName() {

        return name;
    }
}

I added a deleteEntry method in the AddressBookEntryImpl which has

public void deleteEntry(String name){

this.name=name;
return name.delete();

}

I got the error:

method deleteEntry in interface AddressBookEntry cannot be applied to given types;
return addressBookEntry.deleteEntry;
required String
found:no arguments
reason: actual and formal argument lists differ in length.

I know that one reason is the return at void I will correct that in a moment. My problem is setting up the arguments and placing the delete().The Entry has fields:

name
mobilenumber
landlinenumber
FirstLineAddress
SecondLineAddress
TownOrCity
Postcode
country

I was referring to your DeleteAddress() method

Ok I have modified the AddressBookGuiImpl class as:

private void DeleteAddress() throws GuiException{

        StringBuffer sb = new StringBuffer( LINE_SEPARATOR );
        sb.append( LINE_SEPARATOR ).append( LINE_SEPARATOR );
        sb.append( DIVIDER ).append( LINE_SEPARATOR );
        sb.append( "Address Book" ).append( LINE_SEPARATOR );
        sb.append( DIVIDER ).append( LINE_SEPARATOR );
        sb.append( LINE_SEPARATOR );

        sb.append( "Please enter the name of the person you wish " +
                "to delete the address details of:" );

        sb.append( LINE_SEPARATOR ).append( LINE_SEPARATOR );


        String name = readInput();

        DeleteAddressActionArgument deleteAddressActionArgument =
            new DeleteAddressActionArgument( name );

        try {
            ActionResult actionResult =
                controller.execute( deleteAddressActionArgument );

            DeleteAddressActionResult deleteAddressActionResult
                = ( DeleteAddressActionResult )actionResult;

            AddressBookEntry addressBookEntry =
                    deleteAddressActionResult.getAddressBookEntry();
        removeAddressBookEntry( addressBookEntry );

        }
        catch( ControllerException e ) {

            throw new GuiException( "Could not retrieve address entry", e );
        }
    }





      private boolean removeAddressBookEntry(AddressBookEntry addressBookEntry ) {



        if ( addressBookEntry != null ) {

            File deleted=new File(addressBookEntry,name);
       return deleted.delete();
        }
        else {

            print( "Could not find entry" );
        }
    }

   private void endApplication() throws GuiException {


   System.exit(0);

   }

But I get the error:

no suitable constructor found for File(AddressBookEntry) File deleted=new File(addressBookEntry);constructor File.File(URI) is not applicable (actual argument AddressBookEntry cannot be converted to URI by method invocation conversion)constructor File.File(File,String) is not applicable(actual and formal argument lists differ in length)constructor File.File(String,String) is not applicable(actual and formal argument lists differ in length) constructor File.File(String) is not applicable(actual argument AddressBookEntry cannot be converted to String by method invocation conversion)constructor File.File(String,File) is not applicable(actual and formal argument lists differ in length)constructor File.File(String,int) is not applicable(actual and formal argument lists differ in length)1 error

well, that's what you get if you call a constructor which doesn't exist.
for instance new File("myFile.txt"); is a valid call, because the File class has a constructor which takes a String as a parameter, but there isn't one which takes a parameter of the type you're trying to pass on to the constructor.

I created a method in address book entry to delete name,mobile numbe,address etc individually but the address book wont start.Now I am trying to figure out a way in which I will call them from another class like the Gui. I must pass that addressBookEntry into the addressBookGuiimpl then probably change it to boolean so that I delete it. I used new File("addressBookEntry"), compiles but does not perform the delete function. It has to accept input(name), search for the name in the address book directory, return the addressbook entry associated with that name and then DELETE the returned entry.
Just like show details but instead of printing the toString(which has name,mobile number, postal address, country,, etc)it should delete them.

I got it!I modified the AddressBookGuiImpl from line 139 above as:

        DeleteAddressActionArgument deleteAddressActionArgument =
                new DeleteAddressActionArgument( name );

            try {



            controller.execute( deleteAddressActionArgument );


            }
            catch( ControllerException e ) {

                throw new GuiException( "Could not retrieve address entry to delete", e );
            }
        catch (NullPointerException e){

            throw new GuiException( "The Entry Does Not Exist", e );
        }


        }

I don't think the problem was with your AddressBookGuiImpl class you must have changed something else for it to work. did you keep the other changes you had made on address book entry? wish I could see all the running code though.
