Java Examples - Traverse Directory
Java ExamplesThe following example demonstrates using the dir.isDirectory() and dir.list() methods of the File class to traverse a directory:
Main.java file
import java.io.File;
public class Main {
public static void main(String[] argv) throws Exception {
System.out.println("Traverse Directory");
File dir = new File("/www/java"); //The directory to traverse
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]));
}
}
}
}
The output of running the above code is:
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.logOther Extensions
