The user cannot replace this class name using the invocation java -jar. Class-Path describes the location of supportLib.jar relative to the location of the library helloWorld.jar. Neither absolute file path, which is permitted in -classpath parameter on the command line, nor jar
GNU Classpath contains classes from the official Java API namespace. Where calls to native code are necessary or highly desired, this is done from a small number of "VM" classes. The name of such a VM class matches the name of the class requiring native methods, plus the additional VM prefix: VMObject, VMString and
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 (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile.

For example, the Java language does not allow client code that accesses the private data of a class to compile. [12] In the C++ language, private methods are visible, but not accessible in the interface; however, they may be made invisible by explicitly declaring fully abstract classes that represent the interfaces of the class.
srcML (source M L) is a document-oriented XML representation of source code. It was created in a collaborative effort between Michael L. Collard and Jonathan I. Maletic.The abbreviation, srcML, is short for Source Markup Language. srcML wraps source code (text) with information from the Abstract Syntax Tree or AST (tags) into a single XML document.
The GCJ runtime-libraries original source is from GNU Classpath project, but there is a code difference between the libgcj libraries. GCJ 4.3 uses the Eclipse Compiler for Java as a front-end. [7] In 2007, a lot of work was done to implement support for Java's two graphical APIs in GNU Classpath: AWT and Swing.
C++ supports multiple inheritance of arbitrary classes. In Java a class can derive from only one class, [1] but a class can implement multiple interfaces [17] (in other words, it supports multiple inheritance of types, but only single inheritance of implementation). Java explicitly distinguishes between interfaces and classes.
