Security features of Java
Java is a programming language with security at its core, which uses a variety of mechanisms to enhance its Security, including:
1. Sandbox environment
Java programs run in a restricted sandbox environment, which limits their access to system resources. A sandbox environment prevents programs from performing unauthorized actions, such as accessing the file system or network.
2. Type Safety
Java is a strongly typed language, which means that it checks data types at compile time to ensure that the data is used correctly. This type checking helps prevent security vulnerabilities such as buffer overflows and type conversion errors.
3. Garbage collection
Java uses an automatic garbage collection mechanism, which releases memory that is no longer used to prevent memory leaks and pointers pointing to invalid memory. This helps prevent program crashes and security vulnerabilities.
4. Bytecode verification
The Java compiler compiles the source code into bytecode, and the bytecode verifier verifies the integrity of the bytecode at runtime. sex. This helps prevent malicious code from entering the program and ensures that the executed code is safe.
5. Security API
Java provides a set of security APIs to help developers write secure applications. These APIs include encryption, authentication, and access control capabilities.
6. Security Framework
Java provides a security framework, such as a security manager and an access control framework, for configuring and controlling the secure behavior of programs.
7. Code Signing
Java supports code signing, which allows developers to sign their applications to verify their provenance and integrity. This prevents malicious code from being passed off as legitimate code.
8. Security Community
Java has an active security community dedicated to identifying and resolving security vulnerabilities. The community regularly releases security updates to fix security issues.

JVM works by converting Java code into machine code and managing resources. 1) Class loading: Load the .class file into memory. 2) Runtime data area: manage memory area. 3) Execution engine: interpret or compile execution bytecode. 4) Local method interface: interact with the operating system through JNI.

JVM enables Java to run across platforms. 1) JVM loads, validates and executes bytecode. 2) JVM's work includes class loading, bytecode verification, interpretation execution and memory management. 3) JVM supports advanced features such as dynamic class loading and reflection.

Java applications can run on different operating systems through the following steps: 1) Use File or Paths class to process file paths; 2) Set and obtain environment variables through System.getenv(); 3) Use Maven or Gradle to manage dependencies and test. Java's cross-platform capabilities rely on the JVM's abstraction layer, but still require manual handling of certain operating system-specific features.

Java requires specific configuration and tuning on different platforms. 1) Adjust JVM parameters, such as -Xms and -Xmx to set the heap size. 2) Choose the appropriate garbage collection strategy, such as ParallelGC or G1GC. 3) Configure the Native library to adapt to different platforms. These measures can enable Java applications to perform best in various environments.

Java code can run on different operating systems without modification, because Java's "write once, run everywhere" philosophy is implemented by Java virtual machine (JVM). As the intermediary between the compiled Java bytecode and the operating system, the JVM translates the bytecode into specific machine instructions to ensure that the program can run independently on any platform with JVM installed.

The compilation and execution of Java programs achieve platform independence through bytecode and JVM. 1) Write Java source code and compile it into bytecode. 2) Use JVM to execute bytecode on any platform to ensure the code runs across platforms.

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),
