A Java Virtual machine (JVM) is an imaginary computer that can run Java code. As long as the interpreter is ported to a specific computer based on the JVM specification description, any compiled Java code can be guaranteed to run on that system. This article begins with a brief introduction to the process of compiling from the Java file to the final execution, followed by a description of the JVM specification. 　　 I.

There's a question on StackOverflow about the comparison between Java and Python, and there are questions about why Java's runtime is called a JVM, and Python is called interpreter.This problem is estimated not many people think, first look at Wikipedia to see the definition of virtual machine.There are 2 definitions of virtual machines, one is a VMware-like system virtual machine, and the other is a virtual machine called a program virtual machine, such as JVM,CLR, which is the most common virt

StatementIn order to improve the quality of teaching, my college is planning to prepare C language teaching materials. "Write the Interpreter in C language" series of articles after finishing will be revenue book "comprehensive Experiment" chapter. Therefore, the main reading of this series of articles for students who have just finished C language (not requiring data structure and other knowledge), so the wording is more verbose, do not be offended.

Assume that a text box in the system allows the user to enter a string expression, such"5 Division 2 multiplication 3 modulo 4 multiplication 6", The system is required to be able to calculate the expression result according to the Java integer multiplication and division operation rules, such as 12. Assume that the system allows the user to input a string expression in a text box, such as"List name age student ID sortby student IDThe system is required to extract student information from the da

　　 I. Introduction In fact, there is no good example to introduce the interpreter mode, because it describes how to form a simple language interpreter, mainly used in the use of object-oriented language development compilers; in practical applications, we may rarely encounter the situation of constructing a language grammar. Although you can hardly use this model, you can still be inspired by it. 　　Ii. De

18.3 interpreter mode Overview The interpreter mode is a design mode that uses a relatively low frequency but is difficult to learn. It is used to describe how to use object-oriented languages to form a simple language interpreter. In some cases, to better describe certain types of problems, we can create a new language that has its own expressions and structures

These two days there are many Python small white to join the learning group, and asked a lot of questions about Pycharm Basic use, today's small series to configure the Python interpreter problem to give you a simple ramble.1, generally, when we start pycharm, if pycharm normal activation, it will go directly into the pycharm, and pycharm often pop-up interface. (If there is a small partner pycharm has not been activated, you can stand in private mess

Design One, primer In fact, there is no good example to introduce the interpreter pattern, because it describes how to form a simple language interpreter, the main application in the use of object-oriented language development compiler; In practical applications, we may rarely encounter the syntax to construct a language. Although you can hardly use this model, it is still possible to get some inspiration

People who work with shell are familiar with shell programming in Unix/Linux. # is mentioned in all shell programming books #! /Bin/bash. What exactly does it contain? What does this string mean for the operating system? You may say, isn't it true that the/bin/bash program will be used to explain the script program? Of course you are right. Let's look at our title. Here we will talk about the interpreter. Let's take a look at what the first sentence i

2006.6.1 Li Jianzhong Motivation) In the process of software building, if the problems in a specific field are complicated and similar models are repeated, the implementation of common programming methods will face frequent changes. In this case, the problem in a specific field is expressed as a sentence under a certain syntax rule, and then an interpreter is constructed to explain such a sentence, so as to solve the problem. Intent) Given a language
