Initially started with Applets (embedded components in a webpage), Java is today the most used platform for web-based applications and web services. The Java programming language was designed to be a machine-independent programming language powerful enough to replace native executable code. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems’ Java platform. A virtual machine, called the Java Virtual Machine (JVM), is used to run the bytecode on each platform. The format of bytecode is platform-independent. WORA is achieved by compiling a Java program into an intermediate language called bytecode. It is intended to let application developers “write once, run anywhere” (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.įor example, we can write and compile a Java program on UNIX and run it on Microsoft Windows, Macintosh, or UNIX machines without any modifications to the source code. Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. Java is considered a fast language, almost as fast as languages like C and Rust, but it uses a lot of memory in comparison to these languages.
