Procedural programming is about writing procedures or methods that perform operations on the data, while object-oriented programming is about creating objects that contain both data and methods. Object-oriented programming has several advantages over procedural programming:
Every class in Java inherits from the Object class, making its methods available to all Java objects. Understanding the methods of the Object class is fundamental to mastering Java programming as these methods provide essential functionality for all objects. This guide covers various methods available in the Object class.
To call a method in Java, write the method name followed by a set of parentheses (), followed by a semicolon (;). A class must have a matching filename (Main and Main.java).
