What is Java?
• General-purpose, class-based, object-oriented programming
language.
• Designed with minimal implementation dependencies.
• Developed by James Gosling at Sun Microsystems (1995).
• Owned by Oracle Corporation.
• Best Java Institute in Pitampura
Java Editions
• Java SE (Standard Edition): Core functionality.
• Java EE (Enterprise Edition): Web & enterprise
apps.
• Java ME (Micro Edition): Mobile & embedded
systems.
• JavaFX: Rich GUI applications.
Key Features of Java
• Platform Independent: Write Once, Run
Anywhere (WORA).
• Object-Oriented: Encapsulation, Inheritance,
Polymorphism, Abstraction.
• Robust & Secure: Exception handling and security
APIs.
• Multithreaded, High Performance, Distributed
computing support.
Java Architecture
• Source Code (.java) → Compiler → Bytecode
(.class) → JVM → Output.
• JVM interprets bytecode for platform
independence.
Java Program Structure
• Example:
• public class HelloWorld {
• public static void main(String[] args) {
• System.out.println("Hello, world!");
• }
• }
Java Development Tools
• JDK (Java Development Kit): Develop Java
applications.
• JRE (Java Runtime Environment): Run Java
applications.
• JVM (Java Virtual Machine): Executes bytecode.
• Popular IDEs: IntelliJ IDEA, Eclipse, NetBeans, VS
Code.
Core Concepts in Java
• Classes & Objects, Data Types, Control
Statements.
• Methods & Constructors, Inheritance &
Polymorphism.
• Interfaces, Abstract Classes, Exception
Handling.
• Packages & Access Modifiers.
OOP Principles in Java
• Encapsulation – Wrapping data and code.
• Abstraction – Hiding implementation details.
• Inheritance – Reusing code across classes.
• Polymorphism – One interface, many
implementations.
Java Libraries & Frameworks
• Collections Framework, I/O and NIO,
Multithreading.
• GUI (AWT, Swing, JavaFX), Networking.
• Popular Frameworks: Spring, Hibernate,
Maven, Gradle.
Real-World Applications of Java
• Enterprise Applications (Banking, CRM).
• Mobile Apps (Android).
• Desktop GUIs, Scientific Applications.
• Web Applications (Spring Boot, JSP), Games.
Java vs Other Languages
• Java vs C++ vs Python:
• Java: Bytecode, Verbose, Safe, Moderate
Speed.
• C++: Native compiled, Fast, Complex syntax.
• Python: Interpreted, Easy syntax, Slower.
Careers & Certifications
• Roles: Java Developer, Backend Engineer,
Android Developer.
• Certifications: OCPJP, Spring Professional
Certification.
• Industries: Finance, Telecom, Healthcare,
SaaS.
Resources to Learn Java
• Books: Head First Java, Effective Java.
• Websites: Oracle Docs, GeeksforGeeks,
JavaTPoint.
• Platforms: Coursera, Udemy, edX.
Summary
• Java is versatile, powerful, and widely used.
• Strong foundation for software development
careers.
• Supports development of robust, scalable
apps.
