Core Java refers to the fundamental features and basic components of the Java programming language. It is the foundation for all other editions of Java such as Advanced Java, Java EE (Enterprise Edition), and Java ME (Micro Edition).
Core Java is used to build standalone applications and teaches the object-oriented programming (OOP) principles that Java is based on.
Platform Independent: Write once, run anywhere (WORA) using the Java Virtual Machine (JVM)
Object-Oriented: Uses concepts like classes, objects, inheritance, polymorphism, encapsulation, and abstraction
Simple and Secure: Syntax is simple and avoids common errors like pointer misuse
Multithreaded: Supports multithreading and concurrent programming
Rich API: Includes packages like java.lang, java.util, java.io, etc.
Java Basics (syntax, variables, data types)
Operators and Control Statements
Classes and Objects
Constructors and Method Overloading
Inheritance and Polymorphism
Abstraction and Interfaces
Exception Handling
Arrays and Strings
Wrapper Classes and Autoboxing
Collections Framework
Multithreading
File Handling (I/O Streams)
Desktop GUI applications
Command-line utilities
Backend logic for software systems
Building the base for Android development
Job after learning Core Java:
Java Developer – Build backend and desktop apps.
Android Developer – Develop mobile apps (Java-based).
QA Automation Engineer – Write test scripts in Java.
Software Engineer – Enterprise app development.
Support Engineer – Maintain Java-based systems.
