How can I access saved Bean values ​​from another class

Question

How can I implement this functionality?

ApplicationConstants.phoneContacts.add( new ContactNumberBean(nameOfContact, contactNumber, contactNumberType)); 

Classes ApplicationConstants and ContactNumberBean

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 send some solution, thanks in advance .... Narasimha

hi to access values ​​in another class, create a generic class called Constants.java in that you declare and initialize the object, as shown below:

 public class Constants{ public static Bean userBeen=new Bean(); } 

there was a 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.
