    In Java, there are four types of inheritance:

    Single Inheritance: In single inheritance, a class inherits properties and methods from only one parent class. The child class extends the parent class and can override its methods or add new methods.

    Multi-level Inheritance: In multi-level inheritance, a class extends another class that has already extended a parent class. This creates a hierarchical structure of classes, where each class inherits properties and methods from its immediate parent class and all the parent classes above it.

    Hierarchical Inheritance: In hierarchical inheritance, multiple child classes inherit properties and methods from a single-parent class. This creates a tree-like structure of classes, where the parent class is at the top and the child classes are at the bottom.

    Multiple Inheritance (through interfaces): Java does not support multiple inheritance of classes, but it does support multiple inheritance through interfaces. An interface is a collection of abstract methods that a class can implement. A class can implement multiple interfaces and inherit their methods.
