I am trying to make a pojo class for recyclerview.

The data I am getting from the json will be like this.

newsfeeddata:{ id:"",

  timestamp:"",

  userdetails:{

     id:""

     profile_pic_url:"",

     name:""

  },

  post:{ (optional)

    id:""

    text:"" 

  },

  media :{ (optional)

    id:""

    url:""

  }

}

In some objects there will be 'post' and in other object instead of 'post' there will be 'media'. How do I make a pojo class for this?

Make separate classes for userdetails, post and media. And use them as instance variable in newsfeeddata class.

public class Post {

    public String id;

    public String text;

}



public class Userdetails {

    public String id;

    public String profile_pic_url;

    public String name;

}



public class Media {

    public String id;

    public String url;

}

Now use an instance of these in your newsfeeddata class.

public class Newsfeeddata {



    public String id;

    public String timestamp;

    public Userdetails userdetails;

    public Post post;

    public Media media;



}

Note:

1. You can change the access-modifier to private and use getters and setters. Read about lombook-data annotation. Using a single @Data annotation above your class, you can have all getters, setters, toString implementation and more. Makes your class concise and pretty.




2. You may want to change data-type of fields. For simplicity, I have used String.
