Determining If Two Filename Paths Refer to the Same File
A filename path may include redundant names such as `.' or `..'
or symbolic links (on UNIX platforms). File.getCanonicalFile()
converts a filename path to a unique canonical form suitable for
comparisons.
File file1 = new File("./filename");
File file2 = new File("filename");
// Filename paths are not equal
boolean b = file1.equals(file2); // false
// Normalize the paths
try {
file1 = file1.getCanonicalFile(); // c:\almanac1.4\filename
file2 = file2.getCanonicalFile(); // c:\almanac1.4\filename
} catch (IOException e) {
}
// Filename paths are now equal
b = file1.equals(file2); // true
