Java递归目录结构

import java.io.File;

public class FileTree {

public static void main(String[] args) {
printFileTree("D:\\AAAAASSOCWEBDATA",0);
}

public static void printFileTree(String driver, int level) {
File file = new File(driver);
printByLevel(file.getName(),level);
if (file.exists()) {
if(file.isDirectory()){
File[] children = file.listFiles();
for (int i = 0; i < children.length; i++) {
printFileTree(children[i].getPath(),level+1);
}
}
}
}

public static void printByLevel(String name,int level) {
for (int i = 0; i < level; i++) {
System.out.print(" ");
}
System.out.println("|-〄"+name);
}

}

结果如下
|-〄AAAAASSOCWEBDATA
