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\")){
    //         


        

Answer 1

You need to iterate your list and call String#trim for searching:

String search = "A";
for(String str: myList) {
    if(str.trim().contains(search))
       return true;
}
return false;

OR if you want to perform ignore case search, then use:

search = search.toLowerCase(); // outside loop

// inside the loop
if(str.trim().toLowerCase().contains(search))
