Java Programming

Pattern p = Pattern.compile("\032");
Matcher m = p.matcher("");

java.util.regex.Matcher;
java.util.regex.Pattern;

I went through api doc but not able to understand. Could you plz explain the pattern meaning of compile("\032") ?? Whether it is simply thrity two
or it has some meaning of octagonal or hexagonal character values ?? For which pattern it will search ?? I believe that code is for special
characters and not for simply thirty two. Plz advise. Similarly could you plz explain the meaning of matcher("") ??

thanks
