plz help...padded with zero error?

Question about the task

Under discussion

public String getPhoneNumber(){ //Integer.toString(int) String.format("%05d", yournumber); return String.format("%010",Integer.toString(this.data.getCountryPhoneCode())+Integer.toString(this.data.getPhoneNumber())); }

Adapt IncomeData to the Customer and Contact interfaces.
The adapter class is IncomeDataAdapter.
Initialize countries before running the program. Mapping between country codes and country names:
UA Ukraine
US United States
FR France
If necessary, pad phone numbers with zeros to get 10 digits long (see the examples).
Pay attention to the format of people's first and last names.

Requirements:

The Solution class must have a public static Map<String, String> field called countries.
Initialize the countries field in a static block in the Solution class using the test data provided in the task.
The IncomeDataAdapter class must implement the Customer and Contact interfaces.
The IncomeDataAdapter class must have a private IncomeData field called data.
The IncomeDataAdapter class must have a constructor with an IncomeData parameter.
Using the hints in the interfaces' comments, implement the methods of the Customer and Contact interfaces in the IncomeDataAdapter class.

package com.codegym.task.task19.task1903; /* Adapting multiple interfaces */ import java.util.HashMap; import java.util.Map; import java.util.Formatter; public class Solution { public static Map<String, String> countries = new HashMap<>(); static{ countries.put("UA","Ukraine"); countries.put("US","United States"); countries.put("FR","France"); } public static void main(String[] args) { } public static class IncomeDataAdapter implements Customer,Contact{ private IncomeData data; public IncomeDataAdapter(IncomeData idata){ this.data=idata; } public String getCompanyName(){ return this.data.getCompany(); } public String getCountryName(){ return countries.get(this.data.getCountryCode()); } public String getName(){ return this.data.getContactLastName()+","+" "+this.data.getContactFirstName(); } public String getPhoneNumber(){ //Integer.toString(int) String.format("%05d", yournumber); return String.format("%010",Integer.toString(this.data.getCountryPhoneCode())+Integer.toString(this.data.getPhoneNumber())); } } public static interface IncomeData { String getCountryCode(); // For example: US String getCompany(); // For example: CodeGym Ltd. String getContactFirstName(); // For example: John String getContactLastName(); // For example: Smith int getCountryPhoneCode(); // For example: 1 int getPhoneNumber(); // For example: 501234567 } public static interface Customer { String getCompanyName(); // For example: CodeGym Ltd. String getCountryName(); // For example: United States } public static interface Contact { String getName(); // For example: Smith, John String getPhoneNumber(); // For example: +38(050)123-45-67 } }

And this?

return String.format("%010d", Integer.parseInt(Integer.toString(this.data.getCountryPhoneCode())+Integer.toString(this.data.getPhoneNumber())));
;

Also, you can test your solution:

public static void main(String[] args) {
    IncomeDataAdapter incomeDataAdapter = new IncomeDataAdapter(new IncomeData() {
        @Override
        public String getCountryCode() {
            return null;
        }

        @Override
        public String getCompany() {
            return null;
        }

        @Override
        public String getContactFirstName() {
            return null;
        }

        @Override
        public String getContactLastName() {
            return null;
        }

        @Override
        public int getCountryPhoneCode() {
            return 3;
        }

        @Override
        public int getPhoneNumber() {
            return 82828281;
        }
    });

    System.out.println(incomeDataAdapter.getPhoneNumber());
}
