Does Java have a path joining method

Question

Exact Duplicate  combine paths in java I would like to know if there is such a method in Java  Take this snippet as example      this will output a b System out println path join  quot a quot   quot b quot        a b  System out println path join  quot a quot   quot  b quot

This concerns Java versions 7 and earlier.

To quote a good answer to the same question:

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();
}

One way is to get system properties that give you the path separator for the operating system  this tutorial explains how   You can then use a standard string join using the file separator

This is a start  I don t think it works exactly as you intend  but it at least produces a consistent result   import java io File   public class Main       public static void main final String   argv          throws Exception               System out println pathJoin             System out println pathJoin               System out println pathJoin  a             System out println pathJoin  a    b             System out println pathJoin  a    b    c             System out println pathJoin  a    b        def                public static String pathJoin final String     pathElements                final String path           if pathElements    null    pathElements length    0                        path   File separator                    else                       final StringBuilder builder               builder   new StringBuilder                 for final String pathElement   pathElements                                final String sanitizedPathElement                      the      is for Windows    you will need to come up with the                     appropriate regex for this to be portable                 sanitizedPathElement   pathElement replaceAll        File separator                        if sanitizedPathElement length    gt  0                                        builder append sanitizedPathElement                       builder append File separator                                                path   builder toString                       return  path
