Folder operation
package com.file; import java.io.File; /** * Created by elijahliu on 2017/2/11. */ public class HelloFolder { public static void main(String[] args) { File folder = new File("my new folder"); if (folder.mkdir()) {//创建文件夹 判断是否成功 System.out.println("文件夹创建完成"); File newfolder = new File("myn new foleder - new"); folder.renameTo(newfolder);//这里重命名了文件夹 文件夹的重命名是可以单独更改一级的文件夹名的 而这一级下面的文件夹不变 保存目录结构 if (folder.delete()) { System.out.print("done");//这里的删除只能删除空文件夹,如果文件夹中有东西,那么则不能删除,不问三七二十一直接删除一个非空文件夹是非常不负责任的 } else { System.out.println("fail"); } }else{ if (folder.exists()) { System.out.println("文件夹已经存在不用创建"); }else{ System.out.println("文件夹创建失败"); } } File folders = new File("my new folder/one/two/three/main"); folders.mkdirs();//在java中用mkdir只能创建一个,mkdirs可以创建多级目录 } }

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),
