Using shared preferences editor

Question

I'm slowly working through an Android learning book and was given the following code to assign user data:

package com.androidbook.triviaquiz;  import android.app.Activity; import android.content.SharedPreferences;  public class QuizActivity extends Activity {     public static final String GAME_PREFERENCES = "GamePrefs";     SharedPreferences settings = getSharedPreferences(GAME_PREFERENCES, MODE_PRIVATE);     SharedPreferences.Editor prefEditor = settings.edit();     prefeditor.putString("UserName", "John Doe"); //**syntax error on tokens**     prefEditor.putInt("UserAge", 22); //**syntax error on tokens**     prefEditor.commit(); } 

However, I get an error (lines indicated with comments) that underlines the period and says "misplaced construct" and also that underlines the arguments saying "delete these tokens". I have seen this done in other applications in the same format, I don't understand what is wrong.

Edit: Of course! Those statements cannot be put directly into the class at that level and must be inside a method, something like this:

public class QuizActivity extends Activity {     public static final String GAME_PREFERENCES = "GamePrefs";      @Override     public void onCreate(Bundle savedInstanceState)     {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);          SharedPreferences settings = getSharedPreferences(GAME_PREFERENCES, MODE_PRIVATE);         SharedPreferences.Editor prefEditor = settings.edit();         prefEditor.putString("UserName", "John Doe");         prefEditor.putInt("UserAge", 22);         prefEditor.putString("Gender", "Male");         prefEditor.commit();     } }
