12,166 PointsTreets program help with Twitter API
I tried to load actual tweets from twitter in this program. I am successfully getting data from twitter and it is saving in a file "tweets.ser" using twitter4j api. But on using the load() method, it seems that the ois.readObject() returns an ResponseListImpl object instead of a Status object. Can someone help me to convert this to a Status obj so I can display it?.
My code: This is the RealTreets.java file using the save and load methods.
I want to save and load my twitter feed by first saving it into tweet.ser file and then using a load() method to retrieve it. But im getting an error: "Exception in thread "main" java.lang.ClassCastException: twitter4j.ResponseListImpl cannot be cast to [Ltwitter4j.Status; at com.teamtreehouse.RealTreets.load(RealTreets.java:25) at Example.main(Example.java:12)"
Here is my code:
import java.io.*;
import java.util.List;
import twitter4j.Status;
public class RealTreets{
public static void save(List<Status> status){
try(
FileOutputStream fos = new FileOutputStream("tweets.ser");
ObjectOutputStream oos = new ObjectOutputStream(fos);
) {
oos.writeObject(status);
}catch(IOException ioe) {
System.out.println("Problem saving Tweets");
ioe.printStackTrace();
}
}
public static Status[] load(){
Status[] status = new Status[0];
try(
FileInputStream fis = new FileInputStream("tweets.ser");
ObjectInputStream ois = new ObjectInputStream(fis);
){
status = (Status[]) ois.readObject();
} catch(IOException ioe){
System.out.println("Error reading file!");
ioe.printStackTrace();
} catch(ClassNotFoundException cnfe){
System.out.println("Error loading treets.");
cnfe.printStackTrace();
}
return status;
}
}
