Core Java Practice Exam

Core Java

Core Java includes concepts such as object-oriented programming (OOP), which allows developers to create modular and reusable code through classes and objects. Core Java also covers essential topics like data types, control flow statements, exception handling, and file I/O. Additionally, it includes the Java API (Application Programming Interface), which provides a set of classes and interfaces for tasks such as string manipulation, date and time handling, and collection management. Core Java is essential for understanding advanced Java concepts and frameworks, making it a fundamental skill for Java developers.
