Java vs Other Languages
Java vs Python: Java is more verbose but faster and type-safe. Better for large enterprise systems; Python is better for quick scripts and data science.
Java vs JavaScript: Different languages despite similar names. Java for backend/Android; JavaScript for web browsers and Node.js.
Java vs Kotlin: Kotlin is modern JVM alternative. Many Android shops prefer Kotlin now, but Java remains enterprise standard.
