The mReleaseDate member variable is already stored as a Date object. Convert it and return it using the SimpleDateFormat

import java.util.Date;

public class Movie {

    private String mTitle;
    private Date mReleaseDate;

    public String getTitle() {
        return mTitle;
    }

    public void setTitle(String title) {
        mTitle = title;
    }

    public Date getReleaseDate() {
        return mReleaseDate;
    }

    public String getFormattedReleaseDate(){
      SimpleDateFormat simpledateformat= new SimpleDateFormat("yyyy-MM-dd");
      //simpledateformat.setmReleaseDate(mReleaseDate);
      String timestring = SimpleDateFormat(mReleaseDate);

    return timestring;
    }

    public void setReleaseDate(Date date) {
        mReleaseDate = date;

    }
}
