Method

intcountMatches(String string, String other)
Returns how many times string contains other. 
if (null == string)
    return 0;
if (null == other)
    return 0;
if (0 >= string.length())
    return 0;
if (0 >= other.length())
    return 0;
...
intcountMatches(String theString, String... sep)
count Matches 
return (theString == null) ? 0 : theString.length() - theString.replace(separator(sep), "").length();
intcountMatches(String[] query, String[] entry)
Counts how many Strings in the entry array start with the Strings of the query array. 
int matches = 0;
int indexOfLastMatchPlusOne = 0;
for (int i = 0; i < query.length && indexOfLastMatchPlusOne < entry.length; i++) {
    for (int j = indexOfLastMatchPlusOne; j < entry.length; j++) {
        if (startsWithIgnoreCase(entry[j], query[i])) {
            indexOfLastMatchPlusOne = j + 1;
            matches++;
return matches;
intcountMatchingLines(Throwable ex, Throwable cause)
Count the number of lines that match between an exception and some cause. 
StackTraceElement[] exElements = ex.getStackTrace();
StackTraceElement[] causeElements = cause.getStackTrace();
int i = 0;
int n = Math.min(exElements.length, causeElements.length);
while (i < n) {
    StackTraceElement exElement = exElements[exElements.length - i - 1];
    StackTraceElement causeElement = causeElements[causeElements.length - i - 1];
    if (!causeElement.equals(exElement))
