Study Notes

Java is a high-level, class-based, object-oriented programming language designed to have minimal implementation dependencies.
It is a general-purpose language intended to allow programmers to write once, run anywhere (WORA), meaning compiled Java code can run on all platforms that support Java without recompilation.

Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture.
The Java runtime provides dynamic capabilities, such as reflection and runtime code modification, not typically available in traditional compiled languages.
Java has fewer low-level facilities than C and C++, despite similar syntax.

Java was originally developed by James Gosling at Sun Microsystems, released in May 1995 as a core component of Sun's Java platform.
Initially designed for interactive television, but it was too advanced for the digital cable television industry at the time.
The language was initially called Oak, later renamed Green, and finally Java, named after a type of coffee from Indonesia.

Java 1.0 was released in 1996, promising write once, run anywhere (WORA) functionality with no-cost run-times on popular platforms.
The first public implementation included configurable security, network- and file-access restrictions.
Major web browsers soon incorporated the ability to run Java applets within web pages, making Java quickly popular.

Java 2 (released as J2SE 1.2 in 1998-1999) introduced multiple configurations for different platforms.
J2EE included technologies and APIs for enterprise applications, while J2ME featured APIs optimized for mobile applications.
In 2006, Sun renamed new J2 versions as Java EE, Java ME, and Java SE, respectively.
As of March 2024, Java 22 is the latest version, with Java 8, 11, 17, and 21 being previous LTS versions still officially supported.
