Seperate ids or values in a string using comma as delimiter

Question

I get a string of unit ids from this:

 String units = FolderUtil.getInstance().getUnits(folderId);

which looks like this:

[1886bec8-334b-4be0-bcb6-3594c7e454b6, 4818dda2-e124-460d-b910-dc0386ceb138, e95cdfcb-14d6-4065-a69d-8f0213e1f8b4]

How can I separate each id so I can pass each value individually into another method?

Here's a working solution using substring instead of replace:

String s1 = "[1886bec8-334b-4be0-bcb6-3594c7e454b6, 4818dda2-e124-460d-b910-dc0386ceb138, e95cdfcb-14d6-4065-a69d-8f0213e1f8b4]";
String s2 = s1.substring(1,s1.length()-1);
String[] ss = s2.split(",");
for (String str : ss) {
        System.out.println(str.trim());
}

Although by looking at that string, it looks like a string representation of an array of strings. Hence, if you developed the getUnits method, I'd advise you to refactor it to return the correct type and not the result of an arrayOfUnits.toString().

Perfect! I couldn't get the for loop right. Thanks! – Jason Feb 26 '16 at 20:29 — Jason, Feb 26 '16 at 20:29

Try this:

String units = FolderUtil.getInstance().getUnits(folderId);
String[] unitParts = units.replace("[","").replace("]", "").split(", ")
