The evolution of the Java technology platform: from J2SE to Java SE
Since the birth of the Java language, it has been prepared for its cross-platform, security and reliability Respected. The evolution of the Java technology platform has been constantly iterating and improving to adapt to evolving technical needs and market trends. This article will focus on two versions of the Java technology platform in its evolution: J2SE and Java SE.
J2SE (Java 2 Standard Edition) is the first major version of the Java technology platform, which was released in 1998. In J2SE, the basic part of the Java language has been improved, and many new features and APIs have been introduced. This makes it easier for developers to develop and deploy Java applications.
In J2SE, the core APIs of the Java language include java.lang, java.util, java.io, etc. These APIs provide basic data structures, input and output operations, and platform-independent methods. In addition, J2SE also introduces the Swing user interface library, which provides powerful and customizable graphical interface components, greatly improving the developer's user experience.
With the popularization of Java technology and the continuous expansion of application scenarios, the functions of J2SE have been unable to meet the growing demand. In order to provide a better development experience and a wider application scope, Sun Microsystems (now Oracle Corporation) released the next version of the Java technology platform in 2006: Java SE (Java Standard Edition).
As a subsequent version of J2SE, Java SE introduces more new features and improvements. The most significant change is the introduction of a modular system, the Java Platform Module System (JPMS). The modular system divides Java's class library into a series of modules so that developers can load and use the required modules on demand instead of loading the entire class library into memory.
In addition, Java SE also introduces some new APIs and tools to better support modern programming requirements. For example, Java SE 8 introduced stream programming (Stream API), allowing developers to process collections more concisely; Java SE 11 introduced reactive programming features to better handle asynchronous tasks.
In addition to introducing new features, Java SE also continuously improves performance, reliability, and security. Each Java SE version improves the garbage collection mechanism to improve the efficiency of memory management. In addition, Java SE has also strengthened its support for security, such as strengthening the class loading mechanism to prevent the injection of malicious code.
Overall, the evolution of the Java technology platform from J2SE to Java SE has witnessed the continuous development and growth of the Java language. Each version released provides developers with more tools and features, allowing Java to find suitable solutions in different application scenarios.
However, with the continuous development of technology, the Java technology platform is still facing new challenges and needs. For example, with the rise of cloud computing and big data, Java needs to better support distributed computing and the ability to process massive data. At the same time, the rise of mobile applications also requires Java to perform better on the mobile terminal.
Therefore, the future Java technology platform needs to continue to evolve and improve to adapt to changing technology and market needs. Whether it is the upgrade of Java SE or new technology applications, Java will continue to leverage its cross-platform, security and reliability advantages to become the preferred programming language and platform for developers.
To sum up, the evolution of the Java technology platform from J2SE to Java SE demonstrates the power and application prospects of the Java language. By continuously introducing new features and improvements, Java provides a better development experience, wider application scope and higher performance in different versions. However, the Java technology platform still needs to continue to evolve to meet new challenges and needs. I believe that with the continuous development of the Java technology platform, Java will continue to play an important role in the field of software development.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
