Help With Android Try/Catch

Question: Inside the "try" block, add an HttpURLConnection variable named "connection". Initialize it using the openConnection() method of the treehouseUrl variable. The openConnection() method returns a URLConnection object, so don't forget to cast it to HttpURLConnection.

Code:

com/example/MainListActivity.java 
package com.example;

import android.os.Bundle;
import android.view.View;
import java.io.IOException;
import java.net.MalformedURLException;
import android.util.Log;

public class MainListActivity extends ListActivity {

    public static final String URL = "teamtreehouse.com";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_list);

        try {
            URL treehouseUrl = new URL(URL);
            HttpURLConnection connection = (HttpURLConnection) treehouseURL.openConnection();
        }
        catch (MalformedURLException e) {
            Log.e("CodeChallenge", "MalformedURLException caught!", e);
        }
        catch (IOException e) {

        }
    }
}

the URL variable is named treehouseUrl, not treehouseURL:

HttpURLConnection connection = (HttpURLConnection) treehouseUrl.openConnection();
