how to use nested class in another class in java?

I have some situation that I want to use inner class of another class in another class. like...

public class ListData {
    public  static class MyData {

        public String textSongName, textArtistName, textDuration, textDownloadPath,
                textSongSize, textAlbumName, textUrl;
        public boolean enable;

        public MyData(String songName, String artistName, String duration,
                String downloadPath, String songSize, String albumName,
                String url, boolean e) {
            textSongName = songName;
         开发者_运维问答   textArtistName = artistName;
            textDuration = duration;
            textDownloadPath = downloadPath;
            textSongSize = songSize;
            textAlbumName = albumName;
            textUrl = url;
            enable = e;
        }
    }

}

now I want to use Mydata class in another.

how can I do this?

Thanks.

ListData.MyData myData = new ListData.MyData();

Static Nested Classes

OuterClass.StaticNestedClass nestedObject = new OuterClass.StaticNestedClass();

Inner Classes

OuterClass.InnerClass innerObject = outerObject.new InnerClass();

More about Nested Classes

If you can create inner class object from other class that is out of scope from your enclosing class than you should use its fully qualified name.... Here , your outer class is ListData and your Inner class is Mydata and we call Mydata from another class eg. YourData.. than we can use below statement..

Syntax : outerclass.innerclass = new outerclass.innerclass();

=> ListData.MyData objectname = new ListData.MyData();

NOTE : this can use only when innner class is static..
