import java.util.regex.Pattern;

public class RegexDemo
{

    public static void main(String[] args)
    {
        /*
         * The inputText variable contains the text to be checked with
         * the regular expression.
         */

        String inputText = "This is the text to be searched "
                + "for occurrences of the http:// pattern.";

        /*
         * The regular expression matches all texts which contains one
         * or more characters (.*) followed by the text http://
         * followed by one or more characters (.*).
         */

        String regex = ".*http://.*";

        /*
         * the Pattern.matches() static method to check if the regular
         * expression (pattern) matches the text. If the regular
         * expression matches the text, then Pattern.matches() returns
         * true. If the regular expression does not match the text
         * Pattern.matches() returns false.
         */

        boolean matches = Pattern.matches(regex, inputText);

        System.out.println("matches = " + matches);

    }
