explain with suitable examples use of shared preference in android programming.

Shared Preferences is a part of Android's API and it allows you to save and retrieve persistent key-value pairs of primitive data types. This is useful when you want to save a small collection of data, such as user settings or application state, without needing to set up a database.

Here's a step-by-step example of how to use Shared Preferences:

1. Create a new Shared Preference file:

SharedPreferences sharedPreferences = getSharedPreferences("MySharedPref",MODE_PRIVATE);

In this line, "MySharedPref" is the name of the Shared Preference file and MODE_PRIVATE is the operation mode.

2. Write data to Shared Preference file:

SharedPreferences.Editor myEdit = sharedPreferences.edit();
myEdit.putString("name", "John");
myEdit.commit();

In these lines, we're creating an Editor object to put values into the Shared Preference file. We're storing a string "John" with the key "name". The commit() method writes the data immediately.

3. Read data from Shared Preference file:

String name = sharedPreferences.getString("name", "");

In this line, we're retrieving the string value that we stored earlier using the key "name". The second parameter is a default value that will be returned if no value is found with the given key.

4. Remove data from Shared Preference file:

myEdit.remove("name");
myEdit.commit();

In these lines, we're removing the value associated with the key "name" from the Shared Preference file.

5. Clear all data from Shared Preference file:

myEdit.clear();
myEdit.commit();

In these lines, we're removing all values from the Shared Preference file.

Remember, Shared Preferences are not suitable for storing large amounts of data or complex hierarchical data structures. For those use cases, consider using a database or a file storage system.
