function of its base class. When the program finds the keyword virtual before the virtual function name, it automatically uses it as a dynamic concatenation processing, that is, it dynamically selects the appropriate member function when the program is running. Virtual functions are a manifestation of C ++ polymorphism. Dynamic Association stipulates that

In-depth understanding of Java Virtual Machines notes Chapter II Java Virtual machine memory area

Introduction??This chapter is about the memory area of the Java virtual machine can be divided into several parts, the book can be divided into five parts: heap, Stack, program counter, method area, local method stack??Where the heap contains an instance of the object??And often said the basic data type, and the object reference is stored in the stack, in fact, is actually stored in the

Java programmers go from stupid birds to cainiao () to Java Virtual Machine (4)-garbage collection mechanism of Java Virtual Machine

The Java language has been at the forefront of programming languages since its appearance. One major reason is that it is related to the platform where Java applications run. We all know that Java applications run on java virtual machines. This greatly reduces the frequency

C + + virtual function virtual, pure virtual function abstract and Java abstraction function, interface interface and abstract class comparison

Because both C + + and Java are object-oriented programming languages, their polymorphism is achieved by virtual functions and abstract functions, respectively.The virtual function of C + + can be overridden in subclasses, and the invocation is judged by the actual object, not by the pointer type (the invocation of the normal function is based on the current poin

In-depth understanding of Java Virtual Machines notes Chapter II Java Virtual machine memory area

??This phrase feels like the nature of the GC .??????1. Procedure Counter (program Counter Register)??A program counter is a small amount of memory space that acts as a line number indicator of the bytecode that is being executed by the current thread . The bytecode interpreter works by changing the value of this counter to select the next byte-code instruction to execute, and the basic functions such as branching, looping, jumping, exception handling, thread recovery, and so on, need to rely on

class, it inherits the virtual function of its base class. When the program discovers the virtual function name, it will automatically be used as a dynamic binder, which is to select the appropriate member function dynamically when the program is run. Virtual functions are a manifestation of C + + polymorphism. The dynamic binder stipulates that a

Reread "in-depth understanding of Java Virtual Machines" v. How do virtual machines execute bytecode? How the virtual machine execution engine works

The class file binary character stream is loaded into memory (method area) through the ClassLoader and virtual machines. After the layout and initialization of the memory, the virtual machine bytecode execution engine can execute the functions defined by the relevant code implementation program. The object that the virtual machine execution engine executes is a m
