以下实例演示了使用 File 类的 dir.isDirectory() 和 dir.list() 方法来遍历目录:

/*

 Main.java
 */

import java.io.File;

public class Main {
   public static void main(String[] argv)
   throws Exception {
      System.out.println("遍历目录");
      File dir = new File("/www/java"); //要遍历的目录
      visitAllDirsAndFiles(dir);
   }
   public static void visitAllDirsAndFiles(File dir) {
      System.out.println(dir);
      if (dir.isDirectory()) {
         String[] children = dir.list();
         for (int i = 0; i < children.length; i++) {
            visitAllDirsAndFiles
            (new File(dir, children[i]));
         }
      }
   }
}

以上代码运行输出结果为:

遍历目录
/www/java
/www/java/Car.class
/www/java/FileUtil.class
/www/java/FileUtil.java
/www/java/HelloWorld.class
/www/java/HelloWorld.java
/www/java/HelloWorldDebug.class
/www/java/HelloWorldDebug.java
/www/java/Main$1.class
/www/java/Main.class
/www/java/Main.java
/www/java/MainClass.class
/www/java/MainClass.java
/www/java/MyClass.class
/www/java/outfilename
/www/java/test.log
