Method

Filetouch(File baseDir, String... segments)
touch 
File f = baseDir;
for (String segment : segments) {
    f = new File(f, segment);
f.getParentFile().mkdirs();
f.createNewFile();
return f;
voidtouch(File f)
Touch a file (see touch(1)). 
if (!f.exists()) {
    FileWriter fw = new FileWriter(f);
    fw.close();
} else {
    f.setLastModified(System.currentTimeMillis());
voidtouch(File f)
touch 
if (f.createNewFile())
    return;
f.setLastModified(System.currentTimeMillis());
voidtouch(File file)
touch 
touch(file, false);
voidtouch(File file)
Touch a file, setting its last modified timestamp to current time 
if (file.exists()) {
    if (!file.setLastModified(System.currentTimeMillis())) {
        throw new IOException("Could not touch file " + file.getAbsolutePath());
} else {
    try {
        File directory = file.getParentFile();
        if (!directory.exists()) {
...
booleantouch(File file)
touch 
FileOutputStream fo = null;
try {
    fo = new FileOutputStream(file);
} catch (Exception e) {
    return false;
} finally {
    if (fo != null) {
        try {
...
voidtouch(File file)
Creates an empty file. 
new FileOutputStream(file).close();
voidtouch(File file)
Implements the same behaviour as the "touch" utility on Unix. 
if (!file.exists()) {
    OutputStream out = openOutputStream(file);
    closeQuietly(out);
boolean success = file.setLastModified(System.currentTimeMillis());
if (!success) {
    throw new IOException("Unable to set the last modification time for " + file);
voidtouch(File file)
Implements the same behaviour as the "touch" utility on Unix. 
if (!file.exists()) {
    OutputStream out = new FileOutputStream(file);
    out.close();
file.setLastModified(System.currentTimeMillis());
voidtouch(File file)
touch 
long timestamp = System.currentTimeMillis();
touch(file, timestamp);
