Understanding Object-Oriented Programming in Java Object-oriented programming (OOP) treats everything as an object, similar to real-world entities. Objects have properties (attributes they know) and behaviors (actions they perform). For example, a pen has attributes like color and brand while its behavior could be writing. In OOP thinking, even simple tasks like adding numbers involve conceptualizing objects that encapsulate both data and functionality.
Creating Objects Through Classes in Java In Java, objects are created using classes which act as blueprints defining their properties and behaviors. This process is akin to how carpenters use detailed designs provided by clients to build tables; the design corresponds to the class file here. The JVM takes this blueprint after compilation into bytecode and generates the actual object for usage within programs.
