arrays - Java, return if trimmed String in List contains String

Question

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

Something like this:

if(myList.contains("A")){
    //true
}else{
    // false
}

The problem is myList can contain un-trimmed data:

{'  A', 'B  ', '  C  '}

I want it to return true if my item 'B' is in the list. How should I do this? I would like to avoid a looping structure.

With Java 8 Stream API:

List<String> myList = Arrays.asList("  A", "B  ", "  C  ");
return myList.stream().anyMatch(str -> str.trim().equals("B"));
