How to remove the last new line (\n)

Question

I have the code below. the if condition is true and it goes into the line inside the IF but when I inspect answerText later, it still has the new line at the end

if(answerText.endsWith("\n")){
     answerText = answerText.substring(0, answerText.length()-2);           
}

Answer 1

answerText = answerText.trim()

public String trim()

Returns a copy of the string, with leading and trailing whitespace omitted.
