public class RegexDemo
{

    public static void main(String[] args)
    {
        isMatch("a{3}", "aaa");
        isMatch("a{3}", "aa");
        isMatch("a{3}", "aaaaaa");
    }

    private static void isMatch(String regex, String inputText)
    {
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(inputText);

        System.out.println("Regex = " + regex + " , " + "InputText = "
                + inputText + " is matching? = " + matcher.matches());
    }

}

Regex = a{3} , InputText = aaa is matching? = true
Regex = a{3} , InputText = aa is matching? = false
Regex = a{3} , InputText = aaaaaa is matching? = false
