pattern = Pattern.compile(Contents of the Pattern: field); matcher = pattern.matcher(Contents of the String: field); matcher.Whatever_method_you_clicked(); Display results;
In Java: field shows how you would have to write the regular
expression as a Java literal string. You can type or paste from and to a Java program
into this area. It is kept in sync with the patternstring.
