How to remove special characters from an ArrayList?

I have an ArrayList like this: [['something:','outside,,']]

and I want to remove all the special characters.

How can I do that ?


Create a regex which matches with your criterias. And then loop through your list.

String myRegex = "[^a-zA-Z0-9]";

int index = 0;
for (String s : list)
    list.set(index++, s.replaceAll(myRegex, ""));
