How can I implement this functionality?
ApplicationConstants.phoneContacts.add(
new ContactNumberBean(nameOfContact,
contactNumber, contactNumberType));
ApplicationConstants and ContactNumberBean classes
ContactNumberBean :
package com.example.AddressBook;
public class ContactNumberBean
{
private String nameOfContact;
private String contactNumber;
private int contactNumberType;
public String getnameOfContact()
{
return nameOfContact;
}
public String getcontactNumber()
{
return contactNumber;
}
public int getcontactNumberType()
{
return contactNumberType;
}
public ContactNumberBean(String nameOfContact, String contactNumber,int contactNumberType)
{
this.nameOfContact=nameOfContact;
this.contactNumber=contactNumber;
this.contactNumberType=contactNumberType;
}
}
ApplicationConstants :
package com.example.AddressBook;
import java.util.ArrayList;
public class ApplicationConstants
{
//String[] phoneContacts =new String[10];
//ArrayList<NameValuePair> list = new ArrayList<NameValuePair>();
/*String s1,s2;
int i1;
ContactNumberBean cb =new ContactNumberBean(str1,str2,i2);
static ArrayList<String> phoneContacts = new ArrayList<String>();
phoneContacts.add(s1);
phoneContacts.add(s2);
phoneContacts.add(i1);*/
how can implemented in this class functionality ................................
**ApplicationConstants.phoneContacts.add(new ContactNumberBean(nameOfContact,
contactNumber, contactNumberType));**
}
please forward some solution thanks in advance ....Narasimha

hi to access been values in another class create a common class named as Constants.java in that declare and initialize been object like below:
public class Constants{
public static Bean userBeen=new Bean();
}
been class:
public class Been {
private string countryName;
public void setCountry(String s) {
this.countryName=s;
}
public String getCountry() {
return countryName;
}
}
set values:
public class A{
String s="India";
Constants.userBeen.setCountry(s);
}
}
get values:
public class B{
String s=Constants.userBeen.getCountry();
}
}
this will work fine.
