Creating Setting in android JAVA using Preferences
What is Preferences?
In Android Java, preferences are user-configurable settings that can be stored in a file or database.
They are a way for users to customize the behavior of an app or to store their personal data.
Preferences are typically implemented using the `Preference` class.
This class provides a number of different types of preferences, such as `SwitchPreference`, `ListPreference`,
and `EditTextPreference`. Each type of preference has a different way of storing and displaying its value.
Preferences can be used to store a wide variety of settings, such as the app's theme,
the user's preferred language, and the user's contact information.
They can also be used to store personal data, such as the user's login credentials or their shopping cart contents.
