How to import constant fields

Question

I want to import my constants which are in package consts and in class Constants. There I have inside classes.

For example I want to use form Capability.DEVICE_NAME instead of Constants.Capability.DEVICE_NAME

public class Constants {
    public class Capability{
        public final static String DEVICE_NAME = "deviceName";
        public final static String PLATFORM_NAME = "platformName";
        public final static String PLATFORM_VERSION = "platformVersion";
        public final static String APP_PACKAGE = "appPackage";
        public final static String APP_ACTIVITY = "appActivity";
    }
}

It have to be in inside classes!

Thank in advance.

Answer 1

You will have to import your class like below

import packageName.Constants.Capability;

You can use as you want like below:

System.out.println(Capability.DEVICE_NAME);  

Or You can make your class static and import as below.

import static com.Constants.*;

Answer 2

This import packagename.Constants.*; should work.

Or you can make the nested class static

public class Constants {
    public static class Capability{
        public final static String DEVICE_NAME = "deviceName";
        public final static String PLATFORM_NAME = "platformName";
        public final static String PLATFORM_VERSION = "platformVersion";
        public final static String APP_PACKAGE = "appPackage";
        public final static String APP_ACTIVITY = "appActivity";
    }
}

and import static:

import static packagename.Constants.*;
