Abstract
This invention relates to a method of loading Java ClassFiles on to a Java Virtual Machine. On a regular JVM the ClassFile are loaded as and when required. In this specification there is described a method of implementing an object oriented program language such as Java on a computer. The method comprises identifying a class, one of the basic building blocks of the language, which is not within the program domain, that is not loaded into the Java a Virtual Machine. Next it introduces to the program domain only the minimum components of the class which are necessary for commencing processing of the class. The class may comprise several blocks of data representing the methods of the class, since the class may only have been identified because one of the methods within the class was referenced then only the block of data representing this method is loaded into the Java Virtual Machine along with the other essential components of the class. Other blocks of data representing methods can be loaded as and when required by the programming domain. Redundant method components may be removed from the program domain to save memory.
