Java, return if trimmed String in List contains String

Question

In Java, I want to check whether a String exists in a List myList.

Something like this:

if(myList.contains(\"A\")){
    //

You can do it in a single line by using regex:

if (myList.toString().matches(".*\\bA\\b.*"))

This code should perform quite well.

BTW, you could build the regex from a variable, like this:

.matches("\\[.*\\b" + word + "\\b.*]")

I added [ and ] to each end to prevent a false positive match when the search term contains an open/close square bracket at the start/end.
