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

Using direct conditions (like ==, !=, !condition) will have a slight performance improvement over the .equals(condition) as in one case you are calling the method from an object whereas direct comparisons are performed directly.
