JVM Components
A given JVM might be implemented as a monolithic program, but it is designed as a set of components. The coarse-grained components are class loader, bytecode interpreter, security manager, garbage collector, thread management, and graphics. Each of these components—except perhaps graphics—has a significant influence on the real-time performance of the JVM.
Class Loading
The first time a Java program uses a class, the JVM finds the class and arranges to have it integrated with the rest of the Java environment.
Class loading includes the following steps.
1. | Find the class in a file with a name derived from the fully qualified name of the class by converting dots to file delimiters (slash on UNIX, backslash on DOS-descended systems) ... |
