Read Json File and Convert to Java Object using Jackson

Let us take a look at how to read a JSON file and convert it into Java Object using Jackson library,

import java.util.Arrays;

public class Album {

        private String artistName;
        private String albumName;
        private int releaseYear;
        private String[] songsList;

        public Album() {}

    public Album(String artistName, String albumName, int releaseYear, String[] songsList) {
        this.artistName = artistName;
        this.albumName = albumName;
        this.releaseYear = releaseYear;
        this.songsList = songsList;
    }

    public String getArtistName() {
        return artistName;
    }

    public void setArtistName(String artistName) {
        this.artistName = artistName;
    }

    public String getAlbumName() {
        return albumName;
    }

    public void setAlbumName(String albumName) {
        this.albumName = albumName;
    }

    public int getReleaseYear() {
        return releaseYear;
    }

    public void setReleaseYear(int releaseYear) {
        this.releaseYear = releaseYear;
    }

    public String[] getSongsList() {
        return songsList;
    }

    public void setSongsList(String[] songsList) {
        this.songsList = songsList;
    }

    @Override
    public String toString() {
        return "Album{" +
                "artistName='" + artistName + '\'' +
                ", albumName='" + albumName + '\'' +
                ", releaseYear=" + releaseYear +
                ", songsList=" + Arrays.toString(songsList) +
                '}';
    }
}

   ]
}
