Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a "blueprint" for creating objects.

Mar 27, 2025 · Java Classes . A class in Java is a set of objects that share common characteristics and common properties. It is a user-defined blueprint or prototype from which objects are created.
