  1. Boolean –> editor.putBoolean("key_name1", true); 
  2. Integer –> editor.putInt("key_name2", "int value");
  3. Float –> editor.putFloat("key_name3", "float value");
  4. Long –> editor.putLong("key_name4", "long value");
  5. String –>editor.putString("key_name5", "string value");

  As it provides wide range of possibilities in storing data it is much helpful, and all the data is store at one place and can be used as many times as possible.
