The following example demonstrates how to suspend a thread:

/*
 author by w3cschool.cc
 SleepingThread.java
 */public class SleepingThread extends Thread {
   private int countDown = 5;
   private static int threadCount = 0;
   public SleepingThread() {
      super("" + ++threadCount);
      start();
   }
   public String toString() { 
      return "#" + getName() + ": " + countDown;
   }
   public void run() {
      while (true) {
         System.out.println(this);
         if (--countDown == 0)
            return;
         try {
            sleep(100);
         }
         catch (InterruptedException e) {
            throw new RuntimeException(e);
         }
      }
   }
   public static void main(String[] args) 
   throws InterruptedException {
      for (int i = 0; i < 5; i++)
      new SleepingThread().join();
      System.out.println("线程已被挂起");
   }}

The output result of running the above code is:

#1: 5
#1: 4
#1: 3
#1: 2
#1: 1
……
#5: 3
#5: 2
#5: 1
线程已被挂起

The five major features of Java are polymorphism, Lambda expressions, StreamsAPI, generics and exception handling. 1. Polymorphism allows objects of different classes to be used as objects of common base classes. 2. Lambda expressions make the code more concise, especially suitable for handling collections and streams. 3.StreamsAPI efficiently processes large data sets and supports declarative operations. 4. Generics provide type safety and reusability, and type errors are caught during compilation. 5. Exception handling helps handle errors elegantly and write reliable software.

The core components of the JVM include ClassLoader, RuntimeDataArea and ExecutionEngine. 1) ClassLoader is responsible for loading, linking and initializing classes and interfaces. 2) RuntimeDataArea contains MethodArea, Heap, Stack, PCRegister and NativeMethodStacks. 3) ExecutionEngine is composed of Interpreter, JITCompiler and GarbageCollector, responsible for the execution and optimization of bytecode.

mPDF

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),

SecLists

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
