Next, the JVM loads the bytecode and interprets it by the execution engine or compiles it into machine code through JIT. At the same time, the JVM is also responsible for class loading, memory management and garbage collection. Then, the class loader (ClassLoader) loads class files from disk or network, and the runtime data area includes heap, stack, method area, etc. for data storage for program operation.
