Getting the last modified date of a file in Java
提问by Supuhstar
I'm making a basic file browser and want to get the last modified date of each file in a directory. How might I do this? I already have the name and type of each file (all stored in an array), but need the last modified date, too.

As in the javadocs for java.io.File:
如在 javadocs 中的java.io.File：
new File("/path/to/file").lastModified()
new File("/path/to/file").lastModified()

Since Java 7, you can use java.nio.file.Files.getLastModifiedTime(Path path):
从 Java 7 开始，您可以使用java.nio.file.Files.getLastModifiedTime(Path path)：
Path path = Paths.get("C:\1.txt");
FileTime fileTime;
try {
fileTime = Files.getLastModifiedTime(path);
printFileTime(fileTime);
} catch (IOException e) {
System.err.println("Cannot get the last modified time - " + e);
}
where printFileNamecan look like this:
哪里printFileName看起来像这样：
private static void printFileTime(FileTime fileTime) {
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy - hh:mm:ss");
System.out.println(dateFormat.format(fileTime.toMillis()));
}
Output:
输出：
10/06/2016 - 11:02:41
