Is there a way to count how many specific characters are in a string?

If you have the string a.b.c.d. in this string.I'd like to count how many there are. I'd like to know if I can find out without a repeat statement.

If you use StringUtils provided by Apache Library, int count = StringUtils.countMatches("a.b.c.d", "."); are available.

In the Spring framework, intocus = StringUtils.countOccurrencesOf("a.b.c.d", "."); is available.
