Both a runtime environment and a software development kit (SDK) are available. The runtime environment includes a JIT compiler developed by Symantec , the standard Java class library from Sun , additional classes providing Macintosh-specific functionality, and the Apple Applet Runner (a lightweight application for running Java applets without ...
The Java virtual machine is an abstract (virtual) computer defined by a specification. It is a part of the Java runtime environment. The garbage collection algorithm used and any internal optimization of the Java virtual machine instructions (their translation into machine code) are not specified. The main reason for this omission is to not ...
The proto-runtime toolkit was created to simplify the creation of parallel runtime systems. [ 3 ] In addition to execution model behavior, a runtime system may also perform support services such as type checking , debugging , or code generation and optimization .
Runtime – when loading a class. In practice this method works by capturing knowledge that the Java compiler has of class flow and annotating the compiled method bytecodes with a synopsis of the class flow information. This does not make runtime verification appreciably less complex, but does allow some shortcuts. [citation needed]
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.
