Source Link

Document

Counts how many times the char appears in the given string.

A null or empty ("") String input returns 0 .

 StringUtils.countMatches(null, *)       = 0 StringUtils.countMatches("", *)         = 0 StringUtils.countMatches("abba", 0)  = 0 StringUtils.countMatches("abba", 'a')   = 2 StringUtils.countMatches("abba", 'b')  = 2 StringUtils.countMatches("abba", 'x') = 0
