📖 About Java
Java was developed by Sun Microsystems (now Oracle) in 1995 with the principle of "Write Once, Run Anywhere". Java is used in Android app development, enterprise software, banking systems, big data (Hadoop, Kafka), and Spring Boot backend development. Java is one of the most in-demand programming languages in the Indian job market.
