My New Favorite Method

Some days I manage to really amuse myself with my work. Today I've added some flare to a method that may otherwise be really boring. So let me introduce you to my new favorite method:

  /** 
     * Flattens the sub directories of <tt>roots</tt> into a single array. 
     * 
     * @param roots The root directories. 
     * 
     * @return The [sorted] subdirectories of <tt>roots</tt>. 
     */ 
    private static File[] merge(File ... roots) 
    { 
        int x = 0; 
        int k = 0; 
        File[][] forest = new File[roots.length][]; 
        for (File sapling : roots) 
        { 
            File[] tree = sapling.listFiles(); 
            if (null != tree) 
            { 
                int leaves = tree.length; 
                if (leaves > 0) 
                { 
                    forest[x++] = tree; 
                    k += leaves; 
                } 
            } 
        } 
        File[] woods = new File[k]; 
        for (k = 0; --x >= 0;) 
        { 
            File[] tree = forest[x]; 
            int leaves = tree.length; 
            System.arraycopy(tree, 0, woods, k, leaves); 
            k += leaves; 
        } 
        Arrays.sort(woods, chipper); 
        return woods; 
    }

It cracks me up sometimes that I get paid to have this much fun.
