Java compiler. A Java compiler is a compiler for the Java programming language. Some Java compilers output optimized machine code for a particular hardware/ operating system combination, called a domain specific computer system. An example would be the now discontinued GNU Compiler for Java. [1]
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere ( WORA ), [16] meaning that compiled Java code can run on all platforms that support Java without the ...
Java 2 introduced the Collections Framework, Java String memory map for constants, a Just In Time (JIT) compiler, and the Swing API for GUIs. Java 1.1 (1997) Java 1.1 introduced Inner Classes, Reflection, Java Beans, and the JDBC API for database access. Java 1.0 (1996) Java 1.0 was the first version of the Java programming language.

Write once, run anywhere ( WORA ), or sometimes Write once, run everywhere ( WORE ), was a 1995 [1] slogan created by Sun Microsystems to illustrate the cross-platform benefits of the Java language. [2] [3] Ideally, this meant that a Java program could be developed on any device, compiled into standard bytecode, and be expected to run on any ...
Java bytecode is used at runtime either interpreted by a JVM or compiled to machine code via just-in-time (JIT) compilation and run as a native application. As Java bytecode is designed for a cross-platform compatibility and security, a Java bytecode application tends to run consistently across various hardware and software configurations.
Since the GNU Compiler Collection's 4.3 release, GCJ (its Java compiler) is using the ECJ parser front-end for parsing Java. Examples of free runtime environments include Kaffe, SableVM and gcj. GNU Classpath is the main free software class library for Java. Most free runtimes use GNU Classpath as their class library.
