    Study Notes

    Java Overview

    • Java is a high-level, class-based, object-oriented programming language designed to have few implementation dependencies.
    • It is a general-purpose language intended to allow programmers to "write once, run anywhere" (WORA) on all platforms that support Java.
    • Java code is typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture.

    Java Characteristics

    • Java's syntax is similar to C and C++, but it has fewer low-level facilities than either of them.
    • The Java runtime provides dynamic capabilities such as reflection and runtime code modification, typically not available in traditional compiled languages.

    History of Java

    • Java was originally developed by James Gosling at Sun Microsystems in 1991.
    • It was initially designed for interactive television but was later renamed Java, inspired by Java coffee from Indonesia.
    • The first public implementation, Java 1.0, was released in 1996, promising WORA functionality and providing no-cost run-times on popular platforms.

    Java Evolution

    • With the release of Java 2 (J2SE 1.2) in 1998-1999, new versions had multiple configurations built for different types of platforms.
    • J2EE included technologies and APIs for enterprise applications, J2ME featured APIs optimized for mobile applications, and the desktop version was renamed J2SE.
    • In 2006, Sun renamed new J2 versions as Java EE, Java ME, and Java SE, respectively.

    Java Today

    • Java is a very popular programming language, ranking third in popularity in 2022 according to GitHub.
    • Although still widely popular, there has been a gradual decline in Java's use in recent years, with other languages using JVM gaining popularity.
    • The latest version of Java is Java 22, with previous LTS versions (8, 11, 17, and 21) still officially supported.
