Question

I hava a List<String> that I need to serialize or make a String representation.

For example I have:

myList.add("Bob");
myList.add("account");
myList.add("userId");

The list can contain variable number of items and I need it to be serialized in this form:

\Bob\-\account\-\userId\

I can do a for loop like:

String ss;

for (String s: myList) {
   s = "\\" + s + "\\";
   ss = s + "-";
}

However there will be a "-" in the tail of the resulting String ss

Or is there a Google Guava function to do this already?

You can easily use Apaches Commons StringUtils:

 String ss = "\\" + StringUtils.join(myList.iterator(), "\\-\\") + "\\";
