The C++ standard library is designed to be minimalistic, providing only a standardised set of general use features, while the Java Class Library and Java Platform Module System (the Java standard library) is much more extensive, providing a much larger comprehensive standardised set of features, such as graphics, UI creation, and more.
The Java Native Interface (JNI) is a foreign function interface programming framework that enables Java code running in a Java virtual machine (JVM) to call and be called by [1] native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.
The separation of the API from its implementation can allow programs written in one language to use a library written in another. For example, because Scala and Java compile to compatible bytecode, Scala developers can take advantage of any Java API. [19] API use can vary depending on the type of programming language involved.
Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte , hence the name bytecode , making it a compact form of data .
The implementation started when Sun began releasing the Java source code under the GPL. As of Java SE 7, OpenJDK is the official Java reference implementation. The goal of Java is to make all implementations of Java compatible. Historically, Sun's trademark license for usage of the Java brand insists that all implementations be compatible.
A common example is the iostream library in C++, which uses the << or >> operators for the message passing, sending multiple data to the same object and allowing "manipulators" for other method calls. Other early examples include the Garnet system (from 1988 in Lisp) and the Amulet system (from 1994 in C++) which used this style for object ...
The official core Java API, contained in the Android (Google), SE (OpenJDK and Oracle), MicroEJ. These packages (java.* packages) are the core Java language packages, meaning that programmers using the Java language had to use them in order to make any worthwhile use of the Java language. Optional APIs that can be downloaded separately.
Java OpenGL (JOGL) is a wrapper library that allows OpenGL to be used in the Java programming language. [ 1 ] [ 2 ] It was originally developed by Kenneth Bradley Russell and Christopher John Kline, and was further developed by the Game Technology Group at Sun Microsystems .
