Question

JAVA How to add array to develop a contact list application for the person class objects developed in this code?

The application will include functionality to add, remove, sort and search the contact list. You should also include a method to output the contents of a contact searched for, and also to output the entire list.

The code:

package BankProg;

public class personal {
   private String facebook;
   public personal() { }
   public personal(String facebook) {
   this.facebook = facebook;
   }
   public String getfacebook() { return facebook; }
   public void setfacebook(String facebook) { this.facebook = facebook; }

}

----------

public class business {
   private String Companyname, linkedlnlink;
   private long Faxnumber;
   public business() { }
   public business(String Companyname, String linkedlnlink, int Faxnumber) {
   this.Companyname = Companyname;
   this.Faxnumber= Faxnumber;
   this.linkedlnlink = linkedlnlink;
   }
   public String getCompanyname() { return Companyname; }
   public void setCompanyname(String Companyname) { this.Companyname = Companyname; }
   public String getlinkedlnlink() { return linkedlnlink; }
   public void setlinkedlnlink(String linkedlnlink) { this.linkedlnlink = linkedlnlink; }
   public long getFaxnumber() { return Faxnumber; }
   public void setFaxnumber(long Faxnumber) { this.Faxnumber= Faxnumber;
   }
}

public class family {
   private String relationship;

   public family() { }
   public family(String relationship) {
   this.relationship = relationship;
   }
   public String getrelationship() { return relationship; }
   public void setrelationship(String relationship) { this.relationship = relationship;

}
}
----------

public class Person {
   private String name, mailID, address, notes;
   private long phoneNumber, birthday;
   public Person() { }
   public Person(String name, String mailID, String address, int phoneNumber, int birthday, String notes) {
   this.name = name;
   this.mailID = mailID;
   this.address = address;
   this.phoneNumber = phoneNumber;
   this.birthday = birthday;
   this.notes = notes;}
   public String getName() { return name; }
   public void setName(String name) { this.name = name; }
   public String getMailID() { return mailID; }
   public void setMailID(String mailID) { this.mailID = mailID; }
   public String getAddress() { return address; }
   public void setAddress(String address) { this.address = address; }
   public long getPhoneNumber() { return phoneNumber; }
   public void setPhoneNumber(long phoneNumber) { this.phoneNumber = phoneNumber;
   }
   public String getnotes() {return notes;}
   public void setnotes(String notes) { this.notes = notes; }
   public long getbirthday() { return birthday; }
   public void setbirthday(long birthday) { this.birthday = birthday;
   }

Answer 1

here is what i made changes .. ok.. i am done with this code ,,, and i am adding the functionality to store the data into ArrayList also to compare remove and search item into it... i hope this will work for you !

here is the code,,, please give me positive rating for my effort ,,, THank You !

the code is --

   }
   }
}

i only made change into test class ,, it is not purely satisfy you as it have some problem ,,, but i will definaltely share the code whenever i get the right solution for you ,, till then please give me a positive rating to encourage my work and effort ..

here the snapshot of the output --

Thank You !
