The memory managed by the Java Virtual Machine includes the following runtime data areas:Program Counter (PCR):1, is a small memory space, can be seen as the current thread executes the byte code of the line number indicator2, for thread-private3, the implementation of the Java method has PCR, when the native method is

invocation with the class (method body) where the method resides, and for Java, the bindings are divided into static and dynamic bindings: Static bindings: That is, pre-binding. The method is already bound before the program executes, and is implemented by the compiler or other linker. For Java, a simple binding that can be understood as the program's compile time. In

1. JVM Life cycle Start. When a Java program is started, a JVM instance is generated, and any class that has the public static void main (string[] args) function can be used as a starting point for the JVM instance to run. Run. Main () is the starting point for the program's initial thread, and any other thread is started by that thread. Die. The JVM exits when all non-daemon threads in the program terminate, and the program can use t
