Method overloading is having multiple methods with the same name but different parameters, while method overriding is having a method in a subclass with the same name and parameters as a method in its superclass.
Inheritance is the ability of a class to inherit properties and methods from its parent class. It allows for code reuse and promotes modularity.
Encapsulation is the practice of hiding the internal details of an object and only exposing a public interface. Abstraction is the process of simplifying complex systems by breaking them down into smaller, more manageable parts.
