Java has introduced several new features in interfaces starting from Java 8 and java 9
significantly enhancing their functionality.
These features allow interfaces to be more flexible and powerful,
enabling the development of more robust and maintainable code.
Below is a detailed description of the key new features introduced in the interfaces

Default Methods (Java 8)
Java 8 introduced default methods in interfaces. These are methods that have a default implementation within the interface itself. This allows you to add new methods to interfaces without breaking existing implementations.
Static Methods (Java 8)
Java 8 also introduced static methods in interfaces. These methods are similar to static methods in classes—they belong to the interface and cannot be overridden by implementing classes.
Private Methods (Java 9)
Java 9 introduced private methods in interfaces, allowing you to define methods that are accessible only within the interface itself. This is useful when you need to avoid code duplication in the default methods or static methods.
Private Static Methods(java 9)
In Java 9, private static methods were introduced in interfaces, enhancing the flexibility and encapsulation of code in interfaces. This feature allows interfaces to have static methods that are private, and are only accessible within the interface itself. Private static methods are not inherited by implementing classes or subclasses.
