Java Virtual Machine ● ● Java is compiled into bytecodes Bytecodes are high-level, machine-independent instructions for a hypothetical machine, the Java Virtual Machine (JVM) ● The Java run-time system provides the JVM ● The JVM interprets the bytecodes during program execution ● ● Since the bytecodes are interpreted, the performance of Java programs slower than comparable C/C++ programs But the JVM is continually being improved and new techniques are achieving speeds comparable to native C++ code
