Traversing the Files and Directories Under a Directory
This example implements methods that recursively visits
all files and directories under a directory.
// Process all files and directories under dir
public static void visitAllDirsAndFiles(File dir) {
process(dir);
if (dir.isDirectory()) {
String[] children = dir.list();
for (int i=0; i<children.length; i++) {
visitAllDirsAndFiles(new File(dir, children[i]));
}
}
}
// Process only directories under dir
public static void visitAllDirs(File dir) {
if (dir.isDirectory()) {
process(dir);
String[] children = dir.list();
for (int i=0; i<children.length; i++) {
visitAllDirs(new File(dir, children[i]));
}
}
}
// Process only files under dir
public static void visitAllFiles(File dir) {
if (dir.isDirectory()) {
String[] children = dir.list();
for (int i=0; i<children.length; i++) {
visitAllFiles(new File(dir, children[i]));
}
} else {
process(dir);
}
}
wonderful it was help!
Thanks, it helped a lot :)
