How to use SharedPreferences in Android Studio Java?

Setting values in Preference:

        

           // Global Variable Declare 
         SharedPreferences sharedpreferences;
         SharedPreferences.Editor;
         
        
           // In onCreate Bundle 
          sharedpreferences = getSharedPreferences(MyPREFERENCES, MODE_PRIVATE);     // or
             
          sharedpreferences = getSharedPreferences("", "");
          
          editor.sharedpreferences.edit();
          
          
          // Data Put 
          editor.putString(Name, n);
          editor.apply();

        

Retrieve data from preference:

  
        
        
        // Global Variable Declare
        SharedPreferences sharedpreferences ;
        
        
         //Data Get Strings
         sharedpreferences = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE); //or
         sharedpreferences = getSharedPreferences("", "");

		 String name = sharedpreferences.getString("name", "No name defined");    //"No name defined" is the default value.
		int idName = sharedpreferences.getInt("idName", 0);   //0 is the default value.
