Removing notes from SharedPreference

To remove the data from SharedPreference, we need the key for the particular data item that we already set as the note ID. To remove the note, we need to pass the ID of the note and context. Using the SharedPreference editor, we will be able to remove the data: 

public static void removeNote(String id, Context context) {
    if (id != null) {
        SharedPreferences sharedPreferences = 
        PreferenceManager.getDefaultSharedPreferences(context);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.remove(id);
        editor.apply();
    }
}

The complete class looks as follows:

package com.ashok.packt.wear_note_1.utils;

import android.content.Context;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;

import com.ashok.packt.wear_note_1.model.Note;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

public class SharedPreferencesUtils {

    public static void saveNote(Note note, Context context) {
        if (note != null) {
            SharedPreferences sharedPreferences =   
            PreferenceManager.getDefaultSharedPreferences(context);
            SharedPreferences.Editor editor = 
            sharedPreferences.edit();
            editor.putString(note.getId(), note.getNotes());
            editor.apply();
        }
    }


    public static List<Note> getAllNotes(Context context) {
        SharedPreferences sharedPreferences = 
        PreferenceManager.getDefaultSharedPreferences(context);
        List<Note> noteList = new ArrayList<>();
        Map<String, ?> key = sharedPreferences.getAll();
        for (Map.Entry<String, ?> entry : key.entrySet()) {
            String savedValue = (String) entry.getValue();

            if (savedValue != null) {
                Note note = new Note(entry.getKey(), savedValue);
                noteList.add(note);
            }
        }
        return noteList;
    }

    public static void removeNote(String id, Context context) {
        if (id != null) {
            SharedPreferences sharedPreferences = 
            PreferenceManager.getDefaultSharedPreferences(context);
            SharedPreferences.Editor editor = 
            sharedPreferences.edit();
            editor.remove(id);
            editor.apply();
        }
    }
}
