1. Why you must learn Java

    ⇒ One of the most popular language. Java currently runs on 60,00,00,00,000 devices.

    ⇒ Rich APIs and Community Support

    ⇒ Object Oriented

    ⇒ High paying and a lot of Jobs

    ⇒ Wide Usage (Web-apps, backend, Mobile apps, enterprise software).

  2. What is a Programming Language

    ⇒ Humans use natural language (like Hindi/English) to communicate

    ⇒ Computers only understand 0/1 or on/off

  3. What is an Algorithm

    ⇒ An algorithm is a step-by-step procedure for solving a problem or performing a task.

    ⇒ Giving instructions to a computer

    ⇒ Instructions: Tells computer what to do.

    ⇒ These instructions are called code.

    ⇒ Human instructions are given in High level languages.

    <aside> 🔒

    Compiler converts high level languages to low level languages or machine code

  4. What is Syntax

    ⇒ Structure of words in a sentence.

    ⇒ Rules of the language.

    ⇒ For programming exact syntax must be followed.

  5. History of Java

    ⇒ Developed by James Gosling at Sun Microsystems (Early 1990s): Originally named 'Oak', later renamed Java in 1995

    ⇒ First Release (1995): Introduced "Write Once, Run Anywhere" concept with cross-platform compatibility

    ⇒ Developed with vision of backward compatibility. Should not break with new version release

    ⇒ Rapid Growth and Diversification (Late 1990s - 2010s): Expanded from web applets to server-side applications; standardized into different editions for various computing platforms.

  6. Magic of Byte Code

  7. How Java Changed the Internet

    ⇒ Portability with Write Once Run Anywhere

    ⇒ Security because of Code running on Virtual Machin

  8. Java Buzzwords

    ⇒ Robust

    → Java is robust due to its strong memory management, exception handling, and type checking mechanisms, which help in preventing system crashes and ensuring reliable performance.

    ⇒ Multithreaded

    → Multithreading in programming is the ability of a CPU to execute multiple threads concurrently, allowing for more efficient processing and task management

    ⇒ Architecture Neutral

    → Java is architecturally neutral because its compiled code (bytecode) can run on any device with a Java Virtual Machine (JVM), regardless of the underlying hardware architecture.

    ⇒ Interpreted and High Performance

    → Java combines high performance with interpretability, as its bytecode is interpreted by the Java Virtual Machine (JVM), which employs Just-In-Time (JIT) compilation for efficient and fast execution.

    ⇒ Distributed

    → Java is inherently distributed, designed to facilitate network based application development and interaction, seamlessly integrating with Internet protocols and remote method invocation

  9. Object Oriented Programming
