In this exercise, you learn how to create threads in Java by extending the Thread class directly, instead of implementing the Runnable interface. By doing this, your class inherits the Thread methods, which makes it easier to manipulate the thread directly, without the need to instantiate a separate thread.
Exercise Steps
Extend the Thread class:
Your class must inherit from Thread and override the run() method.
Class constructor:
Use the super(name) constructor to give the thread a name and start execution by calling start() directly.
Override the run() method:
This method defines the behavior of the thread. Here, the thread prints its name and runs a loop.
Complete Functional Example:
Below is the code:
// Define a classe que estende Thread class MyThread extends Thread { // Constrói uma nova thread MyThread(String name) { super(name); // Nomeia a thread start(); // Inicia a thread } // Começa a execução da nova thread public void run() { System.out.println(getName() + " starting."); try { for (int count = 0; count <p><strong>How the Code Works</strong><br> <strong>Secondary Thread Creation:</strong><br> The "Child #1" thread is created and starts immediately with start().</p> <p><strong>Secondary Thread Execution:</strong><br> The thread executes a loop, printing messages and pausing for 400ms between iterations.</p> <p><strong>Main Thread Execution:</strong><br> Meanwhile, the main thread prints dots (".") at 100ms intervals.</p> <p>Program Output (Example)<br> </p> <pre class="brush:php;toolbar:false">Main thread starting. Child #1 starting. .In Child #1, count is 0 ..In Child #1, count is 1 ...In Child #1, count is 2 ... (continua) Main thread ending. Child #1 terminating.
Observations
The main and secondary threads run simultaneously.
The run() method contains the logic of the secondary thread, while the main thread continues its independent execution.

Java implementation "write once, run everywhere" is compiled into bytecode and run on a Java virtual machine (JVM). 1) Write Java code and compile it into bytecode. 2) Bytecode runs on any platform with JVM installed. 3) Use Java native interface (JNI) to handle platform-specific functions. Despite challenges such as JVM consistency and the use of platform-specific libraries, WORA greatly improves development efficiency and deployment flexibility.

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),
