Certification in Core Java

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.

Key Features of Core Java

• 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.
  
  

Main Topics Covered in Core Java

• 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)
  
  

Applications of Core Java

• 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.
