SharedPreferences Not Saving after creating separate class for it

Iam developing an App where iam saving the values in SharedPrefernces. I've created a separate class SharedPreferenceforAlarm for setting or getting the values stored in SharedPreferences. To set or get the stored values, iam calling the class object from different activities.

The problem which iam facing is that the values are not saving correctly.

For example(see the code):

Default value for alarmisSet: False

Default value for alarmName : No Alarm

If iam calling setAlarm(this, true) from any activity, the Log what iam getting is "SHAREDPREFERENCES, Alarm is set: false;"

Same case if iam calling setAlarmName(), default alarmName is printing not the one iam giving.
