Android - Cannot Access SharedPreferences Booleans - Nothing Appears In LogCat - sharedpreferences

Question

I've implemented an instance of shared preferences using the following method:
STARTPOINT:
SharedPreferences prefs=getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor=prefs.edit();
editor.putBoolean("name",true);
editor.putBoolean("cap",true);
editor.putBoolean("code",true);
editor.putBoolean("time",true);
editor.putBoolean("ssid",true);
editor.commit();
ENDPOINT:
SharedPreferences prefs = getSharedPreferences(NDEF_PREF, Context.MODE_PRIVATE);
boolean name = prefs.getBoolean("name", true);
boolean cap= prefs.getBoolean("cap", true);
boolean code = prefs.getBoolean("code", true);
boolean time = prefs.getBoolean("time", true);
boolean ssid = prefs.getBoolean("ssid", true);
TEST METHOD:
Boolean isTrue;
isTrue = null; // valid
isTrue = true; // valid
isTrue = false; // valid
if (isTrue == null) {
Log.d(TAG, "Working Boolean!!!");
and
Boolean isTrue;
isTrue = null; // valid
isTrue = true; // valid
isTrue = false; // valid
if (isTrue != null) {
Log.d(TAG, "NON Working Boolean!!!");
RESULT:
Nothing Appears In LogCat using either method
QUESTION:
Did I implement everything correctly? If so - why can't I null check my new shared preferences?

Answer 1

I have try below code and guess what its show in logcat "val if null"
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SharedPreferences pref = getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = pref.edit();
editor.putBoolean("name", true);
SharedPreferences prefs = getSharedPreferences("prefs",0);
// Boolean val=prefs.getBoolean("name1", true);
Boolean val=null;
//Log.e("vaaa00", ""+val.toString());
if(val!= null)
Log.e("val if ", ""+val);
else
Log.e("val else", ""+val);
}
