0N/AClasses for matching character sequences against patterns specified by regular
0N/Aexpressions.
0N/A
0N/A<p> An instance of the {@link java.util.regex.Pattern} class represents a
0N/Aregular expression that is specified in string form in a syntax similar to
0N/Athat used by Perl.
0N/A
0N/A<p> Instances of the {@link java.util.regex.Matcher} class are used to match
0N/Acharacter sequences against a given pattern. Input is provided to matchers via
0N/Athe {@link java.lang.CharSequence} interface in order to support matching
0N/Aagainst characters from a wide variety of input sources. </p>
0N/A
0N/A<p> Unless otherwise noted, passing a <tt>null</tt> argument to a method
0N/Ain any class or interface in this package will cause a
0N/A{@link java.lang.NullPointerException NullPointerException} to be thrown.
