The following example demonstrates using the dir.list() method of the File class to find a list of all files in the specified directory:
/* author by w3cschool.cc Main.java */import java.io.File;public class Main { public static void main(String[] argv) throws Exception { File dir = new File("../java"); String[] children = dir.list(); if (children == null) { System.out.println("该目录不存在"); } else { for (int i = 0; i < children.length; i++) { String filename = children[i]; System.out.println(filename); } } }}
The output result of running the above code is:
Car. classFileUtil.class FileUtil.java HelloWorld.class HelloWorld.java HelloWorldDebug.class HelloWorldDebug.java ……
The above is Java Example - Search the contents of a file in the specified directory. For more related content, please pay attention to the PHP Chinese website (www.php.cn)!

Java code will have performance differences when running on different platforms. 1) The implementation and optimization strategies of JVM are different, such as OracleJDK and OpenJDK. 2) The characteristics of the operating system, such as memory management and thread scheduling, will also affect performance. 3) Performance can be improved by selecting the appropriate JVM, adjusting JVM parameters and code optimization.

Reasons for writing platform-specific code in Java include access to specific operating system features, interacting with specific hardware, and optimizing performance. 1) Use JNA or JNI to access the Windows registry; 2) Interact with Linux-specific hardware drivers through JNI; 3) Use Metal to optimize gaming performance on macOS through JNI. Nevertheless, writing platform-specific code can affect the portability of the code, increase complexity, and potentially pose performance overhead and security risks.

Java will further enhance platform independence through cloud-native applications, multi-platform deployment and cross-language interoperability. 1) Cloud native applications will use GraalVM and Quarkus to increase startup speed. 2) Java will be extended to embedded devices, mobile devices and quantum computers. 3) Through GraalVM, Java will seamlessly integrate with languages such as Python and JavaScript to enhance cross-language interoperability.

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),
