▶ What Java Is ?
- A verbose, boilerplate-heavy, object-oriented language.
- Created during the dot-com bubble by Sun Microsystems.
- Originally meant for TV remotes, released publicly in 1996.
- Runs on billions of devices for decades.
▶ Java Philosophy
- Motto: "Write once, run everywhere"
- Reality: "Write once, debug everywhere"
- Known for long logs, heavy configuration, and legacy systems.
▶ Ecosystem & Influence
- Inspired JVM languages: Groovy, Clojure, Scala, Kotlin.
- Also indirectly inspired JavaScript.
- Failed attempt at the web: Java Applets (thankfully dead).
▶ Enterprise Reality
- Often paired with Oracle Database.
- Companies spend years talking about migrating away.
- Expensive licenses, long-term enterprise lock-in.
▶ Getting Started Pain
- Install JDK, JRE, JVM.
- Prepare for massive error logs.
- Memorize: public static void main(String[] args)
▶ Java Coding Style
- Forced Object-Oriented Programming.
- Requires classes even for Hello World.
- Much more boilerplate than languages like Python.
- Encourages deep inheritance and complex class hierarchies.
▶ Typical Java Project Lifecycle
- Write one giant class.
- Boss complains.
- Split into deeply nested subclasses.
- Code becomes impossible to refactor.
- Developer questions life choices.
▶ Final Truth
- Java is widely hated yet widely used.
- Two types of languages: 1) Those people complain about 2) Those nobody uses
- Love it or hate it, Java gets real work done.
