Question

如何实现此功能？

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

ApplicationConstants和ContactNumberBean类

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));**


}

请提前感谢一些解决方案...... Narasimha

嗨访问另一个类中的值，创建一个名为Constants.java的公共类，声明并初始化为对象，如下所示：

public class Constants{

    public static Bean userBeen=new Bean();

}

上课：

public class Been {

    private string countryName;

    public void setCountry(String s) {
        this.countryName=s;
    } 

    public String getCountry() {
        return countryName;
    }
}

设定值：

public class A{

    String s="India";

    Constants.userBeen.setCountry(s);

    }
}

获取值：

public class B{

    String s=Constants.userBeen.getCountry();

    }

}

这样可以正常工作。
