Answer 1

following are my classes which i have created ....
customer.java :
package org.ushan.wssample.ws;
public class Customer {
     private String cid;
     private String name;
     private int phone;
     private int home;
     private String street;
     private String town;
     private int age;
     private double balance;
     public Customer(String cid, String name, int phone, int home, String street, String town, int age, double balance){
          this.cid = cid;
          this.name = name;
          this.phone = phone;
          this.home = home;
          this.street = street;
          this.town = town;
          this.age = age;
          this.balance = balance;
     public String getCid() {
          return cid;
     public void setCid(String cid) {
          this.cid = cid;
     public String getName() {
          return name;
     public void setName(String name) {
          this.name = name;
     public int getPhone() {
          return phone;
     public void setPhone(int phone) {
          this.phone = phone;
     public int getHome() {
          return home;
     public void setHome(int home) {
          this.home = home;
     public String getStreet() {
          return street;
     public void setStreet(String street) {
          this.street = street;
     public String getTown() {
          return town;
     public void setTown(String town) {
          this.town = town;
     public int getAge() {
          return age;
     public void setAge(int age) {
          this.age = age;
     public double getBalance() {
          return balance;
     public void setBalance(double balance) {
          this.balance = balance;
}CustomerDatabase.java :
package org.ushan.wssample.ws;
import java.util.*;
public class CustomerDatabase {
     private static List<Customer> customers;
     public static List<Customer> list(){
          return customers;
     public static Customer getCustomer(String cid){
          Iterator<Customer> iterator = customers.iterator();
          while (iterator.hasNext()){
               Customer customer = iterator.next();
               if (customer.getCid().equals(cid)){
                    return customer;
          return null;
     static {
          initCustomers();
     static void initCustomers(){
          customers = new ArrayList<Customer>();
          customers.add(new Customer("AAA", "Ushan", 239875456, "Kandy", 25, 25000.00));
          customers.add(new Customer("BBB", "Gayan", 567567787, "Colombo", 26, 35000.00));
          customers.add(new Customer("CCC", "Kasun", 345689745, "Galle", 24, 15000.00));
}CustomerService.java :
package org.ushan.wssample.ws;
import java.util.List;
public class CustomerService {
    public String getNameForCustomer(String cid){
        return CustomerDatabase.getCustomer(cid).getName();
    public int getPhoneForCustomer(String cid){
        return CustomerDatabase.getCustomer(cid).getPhone();
    public String getAddressForCustomer(String cid){
        return CustomerDatabase.getCustomer(cid).getAddress();
    public int getAgeForCustomer(String cid){
        return CustomerDatabase.getCustomer(cid).getAge();
    public double getBalanceForCustomer(String cid){
        return CustomerDatabase.getCustomer(cid).getBalance();
    public String listAllCustomers(){
        List<Customer> customers = CustomerDatabase.list();
        StringBuilder result = new StringBuilder();
        for(Customer customer : customers){
            result.append(customer.getCid() + " ");
        return result.toString();
}i hav done up to here.i don't know how to include the address object in this.
