By using encapsulation, we can create classes in different modes such as read-only and write-only mode. Another benefit of encapsulation is that we reduce human error because we write code in a proper manner and suitable. Let’s consider a simple example of a washing machine; in this scenar...
Python performs name mangling for attributes that start with double underscores '__'. This means the attribute name gets modified by adding '_classname' in front of it. For example, if you have an attribute named '__value' in a class named "MyClass", it will be stored as '_MyClass__...

In cybersecurity, encapsulation strengthens data protection by ensuring sensitive variables remain inaccessible unless explicitly permitted. For example, encryption libraries often encapsulate cryptographic keys, preventing unauthorized access even if other parts of the system are compromised....
ExampleIn the following example, we create a rectangle class in which we use the private member variable to hide the member variable −Open Compiler using System; namespace RectangleApplication { class Rectangle { //member variables private double length; private double width; public void Accept...

In PHP, the class members (both member variables as well as member functions) are public by default.ExampleIn the following program, the member variables title and price of the object are freely accessible outside the class because they are public by default, if not otherwise specified....
