遞歸文件夾

1. JAVA遍歷一個文件夾中的所有文件---(遞歸)

public void traverseFolder2(String path) {

File file = new File(path);

if (file.exists()) {

File[] files = file.listFiles();

if (null == files || files.length == 0) {

System.out.println("文件夾是空的!");

return;

} else {

for (File file2 : files) {

if (file2.isDirectory()) {

System.out.println("文件夾:" + file2.getAbsolutePath());

traverseFolder2(file2.getAbsolutePath());

} else {

System.out.println("文件:" + file2.getAbsolutePath());

}

}

}

} else {

System.out.println("文件不存在!");

}

}

public void traverseFolder1(String path) {

int fileNum = 0, folderNum = 0;

File file = new File(path);

if (file.exists()) {

LinkedList<File> list = new LinkedList<File>();

File[] files = file.listFiles();

for (File file2 : files) {

if (file2.isDirectory()) {

System.out.println("文件夾:" + file2.getAbsolutePath());

list.add(file2);

foldeNum++;

} else {

System.out.println("文件:" + file2.getAbsolutePath());

fileNum++;

}

}

File temp_file;

while (!list.isEmpty()) {

temp_file = list.removeFirst();

files = temp_file.listFiles();

for (File file2 : files) {

if (file2.isDirectory()) {

System.out.println("文件夾:" + file2.getAbsolutePath());

list.add(file2);

folderNum++;

} else {

System.out.println("文件:" + file2.getAbsolutePath());

fileNum++;

}

}

}

} else {

System.out.println("文件不存在!");

}

System.out.println("文件夾共有:" + folderNum + ",文件共有:" + fileNum);

}
