How to compare Boolean?

Question

Take this for example (excerpt from Java regex checker not working):

while(!checker) {
    matcher = pattern.matcher(number);
    if(matcher.find())
                 


        

Answer 1

.equals(false) will be slower because you are calling a virtual method on an object rather than using faster syntax and rather unexpected by most of the programmers because code standards that are generally used don't really assume you should be doing that check via .equals(false) method.
