How to get String after a certain character using pattern matching?

String tect = "A to B";
Pattern ptrn = Pattern.compile("\\b(A.*)\\b");
Matcher mtchr = ptrn.matcher(tr.text()); 
while(mtchr.find()) {
    System.out.println( mtchr.group(1) );
}

I am getting output A to B but I want to B.

Please help me.
