Java_Programming_Presentation.pptx best institute in prr
- 1. Introduction to JavaProgramming • Powering Billions of Devices Worldwide • Presented by: PARVEEN KUMAR • Learn with DICS the Best institute • Date:01 /07/2025
- 2. 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
- 3. Java Editions • JavaSE (Standard Edition): Core functionality. • Java EE (Enterprise Edition): Web & enterprise apps. • Java ME (Micro Edition): Mobile & embedded systems. • JavaFX: Rich GUI applications.
- 4. Key Features ofJava • 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.
- 5. Java Architecture • SourceCode (.java) → Compiler → Bytecode (.class) → JVM → Output. • JVM interprets bytecode for platform independence.
- 6. Java Program Structure •Example: • public class HelloWorld { • public static void main(String[] args) { • System.out.println("Hello, world!"); • } • }
- 7. 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.
- 8. Core Concepts inJava • Classes & Objects, Data Types, Control Statements. • Methods & Constructors, Inheritance & Polymorphism. • Interfaces, Abstract Classes, Exception Handling. • Packages & Access Modifiers.
- 9. OOP Principles inJava • Encapsulation – Wrapping data and code. • Abstraction – Hiding implementation details. • Inheritance – Reusing code across classes. • Polymorphism – One interface, many implementations.
- 10. Java Libraries &Frameworks • Collections Framework, I/O and NIO, Multithreading. • GUI (AWT, Swing, JavaFX), Networking. • Popular Frameworks: Spring, Hibernate, Maven, Gradle.
- 11. Real-World Applications ofJava • Enterprise Applications (Banking, CRM). • Mobile Apps (Android). • Desktop GUIs, Scientific Applications. • Web Applications (Spring Boot, JSP), Games.
- 12. Java vs OtherLanguages • Java vs C++ vs Python: • Java: Bytecode, Verbose, Safe, Moderate Speed. • C++: Native compiled, Fast, Complex syntax. • Python: Interpreted, Easy syntax, Slower.
- 13. Careers & Certifications •Roles: Java Developer, Backend Engineer, Android Developer. • Certifications: OCPJP, Spring Professional Certification. • Industries: Finance, Telecom, Healthcare, SaaS.
- 14. Resources to LearnJava • Books: Head First Java, Effective Java. • Websites: Oracle Docs, GeeksforGeeks, JavaTPoint. • Platforms: Coursera, Udemy, edX.
- 15. Summary • Java isversatile, powerful, and widely used. • Strong foundation for software development careers. • Supports development of robust, scalable apps.
