PURPOSE: A virtual machine is provided which can be used for a long period, reused, and extended by allowing a run-time class, needed to place the virtual machine in operable mode, include a common heap to be loaded, linked, verified, initialized, and compiled. CONSTITUTION: A read-only part (44) is used to store a code which is not characteristic of an application and a read/write part (46) provides a memory area to be read and written by an application (22 or 24) by using proper lock protection for evading a collision. A dedicated heap (30) can be accessed by only the application (22) and a dedicated heap (36) can be accessed by only the application (24), but the common heap (42) can be accessed by both the applications (22 and 24). A runtime class is loaded and linked to the common heap (42) and the virtual machine can, therefore, use it.
