Get the "last modified" date from a fileTag(s): IO
Simply use the lastModified() method from a file object. but the return value is
system dependent and should only be used to compare with other values returned by
last modified. It should not be interpreted as an absolute time.
String s1 = "file1.dat";
String s2 = "file2.dat";
File f1 = new File(s1);
File f2 = new File(s2);
if (f1.lastModified() < f2.lastModified())
System.out.println((s1 + " IS OLDER THAN " + S2);
