Java Utililty Methods String Char Count

int countChar(String s, char c)
count Char

System.out.println("C:" + c);
int n = 0;
for (char c1 : s.toCharArray()) {
 System.out.println("C1:" + c1);
 if (c1 == c) {
 n++;
 System.out.println("Ntres" + n);
 System.out.println("Nbis:" + n);
return n;

int countChar(String s, char c)
Count the number of times a given character occurs in a String:

int count = 0;
int start = 0;
while ((start = s.indexOf(c, start) + 1) != 0)
 count++;
return count;

int countChar(String s, char c)
Count the number of occurrence of the given chararcter in the given string

int count = 0;
if (s != null) {
 int i = s.indexOf(c);
 while (i >= 0) {
 count++;
 i = s.indexOf(c, i + 1);
return count;

int countChar(String sql, int end)
count Char

int count = 0;
boolean skipChar = false;
for (int i = 0; i < end; i++) {
 if (sql.charAt(i) == '\'' && !skipChar) {
 count++;
 skipChar = false;
 } else if (sql.charAt(i) == '\\') {
 skipChar = true;
...

int countChar(String src, char c)
count Char

if (isNullOrNone(src)) {
 return 0;
int k = 0;
for (int i = 0; i < src.length(); i++) {
 if (src.charAt(i) == c) {
 k++;
return k;

int countChar(String str, char c)
count Char

char[] chars = str.toCharArray();
int count = 0;
for (char d : chars) {
 if (d == c) {
 count++;
return count;
...

int countChar(String str, char c)
count Char

if (str == null || str.isEmpty())
 return 0;
final int len = str.length();
int cnt = 0;
for (int i = 0; i < len; ++i) {
 if (c == str.charAt(i)) {
 ++cnt;
return cnt;

int countChar(String str, char chr)
Returns the number of occurrences of a specific character.

int count = 0;
for (char c : str.toCharArray()) {
 if (c == chr) {
 count++;
return count;

int countChar(String str, char reg)
count Char

char[] ch = str.toCharArray();
int count = 0;
for (int i = 0; i < ch.length; ++i) {
 if (ch[i] == reg) {
 if (ch[i + 1] == reg) {
 ++i;
 continue;
 ++count;
return count;

int countChar(String string, char c, int pos, boolean forwards)
Count how many times a character is repeated in a string, starting at a given position and moving forwards or backwards.

int count = 0;
int increment = 1;
if (!forwards)
 increment = -1;
for (int i = pos; i >= 0 && i < string.length(); i += increment) {
 char c2 = string.charAt(i);
 if (c2 == c)
 count++;
