How to implement the fuzzy matching function of regular expressions
这次给大家带来正则表达式的模糊匹配功能如何实现,实现正则表达式模糊匹配功能的注意事项有哪些,下面就是实战案例,一起来看一下。
本文实例讲述了正则表达式实现字符的模糊匹配功能。分享给大家供大家参考,具体如下:
package com.cn.util; import java.util.regex.Pattern; /** * 正则表达式 工具类 * * @author lifangyu */ public class RegexUtil { /* * IP地址的匹配标达式 ( // \\d{1,3}) // :\d // 0~9数字,{1,3} // 至少一位,最多三位) */ private static String regex_IP = "^(121.15.215.(\\d{1,3}))$"; /* * 字符串 模糊匹配 :^(.*张三.*name.*)$ ; 等值匹配 ^(张三)$ */ private static String regex_containStr = "^(.*张三.*name.*)$"; /* * 字符不包含特定字符串的表达式 */ private static String regex_notcontainStr = "^(?!.*(转发)).*$";// 不包含特定字符串的表达式 public static void main(String[] args) { System.out.println(StringMatchRule("这个邮件 是转发的!", regex_notcontainStr)); } public static boolean StringMatchRule(String souce, String regex) { boolean result = false; if (regex != null && souce != null) { result = Pattern.matches(regex, souce); } return result; } }

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

The power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting. Have you ever wondered why JavaScr
