Java Utililty Methods String Substring Count

int countSubString(final String aString, final String aSubString)
count Sub String

if (aString == null || aSubString == null || aString.isEmpty() || aString.length() < aSubString.length()) {
 return -1;
String[] wSplited = aString.split(aSubString);
return wSplited.length - 1;

int countSubstring(final String text, final String substring)
Cuenta las repeticiones de una subcadena dentro de una cadena.

int count = 0;
for (int i = 0; i <= text.length() - substring.length(); i++) {
 if (substring.charAt(0) == text.charAt(i)
 && substring.equals(text.substring(i, i + substring.length()))) {
 count++;
 i += substring.length() - 1;
return count;

int countSubString(String str, String substr)
count Sub String

int cnt = 0;
int lastindex = str.length();
while (lastindex > -2) {
 lastindex = str.lastIndexOf(substr, lastindex) - 1;
 if (lastindex > -2)
 cnt++;
return cnt;
...

int countSubstring(String string, String substring)
count Substring

int searchFrom = -1;
int count = 0;
do {
 searchFrom = string.indexOf(substring, searchFrom + 1);
 if (searchFrom != -1) {
 count++;
} while (searchFrom != -1);
...

int countSubString(String strToFind, String strSearch)
count Sub String

try {
 int intCount = 0;
 for (int intFromIndex = 0; intFromIndex > -1; intCount++) {
 intFromIndex = strToFind.indexOf(strSearch, intFromIndex + ((intCount > 0) ? 1 : 0));
 return intCount - 1;
} catch (Exception Ex) {
 return -1;
...

int countSubstringOccurrances(String s1, String SubString)
return the number of times the substring occurs in the text - where there are overlaps the count tells how many times the substring could be replaced

int count = 0;
int index = s1.indexOf(SubString);
int sublength = SubString.length();
int start = 0;
while (index > -1) {
 count++;
 start = index + sublength;
 if (start > s1.length() - sublength)
...

int countSubstrings(String string, String sub)
Counts the number of substring in a string

int count = 0;
int index = -1;
while ((index = string.indexOf(sub, index + 1)) != -1) {
 ++count;
return count;
