Example Java Code for Facebook App

Here's a simple example of a Java Facebook app that logs in a user and retrieves their profile information:

import com.facebook.Facebook;
import com.facebook.FacebookException;
import com.facebook.FacebookSdk;
import com.facebook.GraphRequest;
import com.facebook.GraphResponse;
import com.facebook.login.LoginResult;
public class FacebookApp 
    private static final String APP_ID = "YOUR_APP_ID";
    private static final String APP_SECRET = "YOUR_APP_SECRET";
public static void main(String[] args) 
        // Initialize Facebook SDK
        FacebookSdk.init(APP_ID, APP_SECRET);
// Log in user
        LoginResult loginResult = Facebook.getCurrentAccessToken();
        if (loginResult != null) 
            // Get user profile information
            GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() 
                @Override
                public void onCompleted(JSONObject object, GraphResponse response) 
                    if (response.getError() == null) 
                        String name = object.optString("name");
                        String email = object.optString("email");
                        System.out.println("Name: " + name + ", Email: " + email);
                     else 
                        System.out.println("Error: " + response.getError().getErrorMessage());
);
            request.executeAsync();
         else 
            System.out.println("User is not logged in");
