Improved techniques for representation of objects in a Java programming environment are disclosed. The techniques are highly suitable for representation of Java objects inside virtual machines, especially those that operate with limited resources (e.g., embedded systems). A cluster of Java object representations is disclosed. Each of the Java object representations provide a reference to a Java object and a reference to the class associated with the Java object. Accordingly, a two-tier representation is provided which allows efficient implementation of applications which need to access information regarding both Java objects and classes. As a result, quick access to information regarding Java objects can be achieved.
