What is the value of the String `number` after the following code snippet?

```java
SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", MODE_PRIVATE);
Editor editor = pref.edit();
editor.putString("1", "2");
editor.putString("3", "4");
editor.apply();
String number = pref.getString("2", "3");
```

Answer :

Final answer:

In the context of Android development, the value of the variable 'number' after running the provided SharedPreferences code snippet will be "3", as it's the default value provided to the getString method for a key that does not exist.

Explanation:

The provided code snippet is related to Android development, specifically the usage of SharedPreferences which is a mechanism for storing simple data in key-value pairs. After executing the code snippet, the value of the string number will be "3".

This is because the getString method attempts to retrieve the value associated with the key "2", but since there is no value stored with this key, it returns the default value provided, which is "3".
