I know I'm an idiot. But why is the regular expression hitting me with False?

Question

Java

Pattern pattern = Pattern.
                compile("a");
        Matcher a = pattern.matcher("HelsssaoWorld");
        System.out.println(a.matches());

Answer 1

You just don't know how to use regular expressions. ... and googling

Answer 2

System.out.println(a.find());
or so

Pattern pattern = Pattern.
                compile(".*a.*");
        Matcher a = pattern.matcher("HelssshaWorld");
        System.out.println(a.matches());
