/**

public class RegexDemo
{

    public static void main(String[] args)
    {

        /*
         * To match only when the required regex is true at the end of
         * the text, we use the dollar character $.
         */
        calculateMatches("dog$", "Man's best friend is a dog");
        calculateMatches("dog$", "is a dog man's best friend?");
    }

    private static void calculateMatches(String regex, String inputText)
    {
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(inputText);
        int matches = 0;

        /*
         * The find method keeps advancing through the input text and
         * returns true for every match, so we can use it to find the
         * match count as well:
         */
        while (matcher.find())
        {
            ++matches;
        }
        System.out.println("Number of Matches = " + matches);
    }

}

Output

Number of Matches = 1
Number of Matches = 0
