combine paths in java

Question

Hi, Is there a java equivalent for System.IO.Path.Combine of C#? Or any code to accomplish this?

Answer 1

This SO question might help.

Answer 2

Rather than keeping everything string-based, if you use java.io.File, you can do:

File baseDirectory = new File("foo");
File subDirectory = new File(baseDirectory, "bar");
File fileInDirectory = new File(subDirectory, "baz.txt");

If you want it back as a string later, you can call getPath(). Indeed, if you really wanted to mimic Path.Combine, you could just write something like:

public static String combine (String path1, String path2)
{
    File file1 = new File(path1);
    File file2 = new File(file1, path2);
    return file2.getPath();
}

Answer 3

The main answer is to use File objects. However Commons IO does have a class FilenameUtils that can do this kind of thing.
