Java Example - Print Directory Structure
以下实例演示了使用 File 类的 file.getName() 和 file.listFiles() 方法来打印目录结构:
/* author by w3cschool.cc FileUtil.java */import java.io.File;import java.io.IOException;public class FileUtil { public static void main(String[] a)throws IOException{ showDir(1, new File("d:\\Java")); } static void showDir(int indent, File file) throws IOException { for (int i = 0; i < indent; i++) System.out.print('-'); System.out.println(file.getName()); if (file.isDirectory()) { File[] files = file.listFiles(); for (int i = 0; i < files.length; i++) showDir(indent + 4, files[i]); } }}
以上代码运行输出结果为:
-Java -----codes ---------string.txt ---------array.txt -----w3cschoolcc
以上就是Java 实例 - 打印目录结构的内容,更多相关内容请关注PHP中文网(www.php.cn)!

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is

Capsules are three-dimensional geometric figures, composed of a cylinder and a hemisphere at both ends. The volume of the capsule can be calculated by adding the volume of the cylinder and the volume of the hemisphere at both ends. This tutorial will discuss how to calculate the volume of a given capsule in Java using different methods. Capsule volume formula The formula for capsule volume is as follows: Capsule volume = Cylindrical volume Volume Two hemisphere volume in, r: The radius of the hemisphere. h: The height of the cylinder (excluding the hemisphere). Example 1 enter Radius = 5 units Height = 10 units Output Volume = 1570.8 cubic units explain Calculate volume using formula: Volume = π × r2 × h (4
