counting the number of characters in a string java
public static void main(String[] args) {
int wordCount = 0;
String word = "hill";
for (char letter = 'a'; letter <= 'z'; letter++) {
for (int i = 0; i < word.length(); i++) {
if (word.charAt(i) == letter) {
wordCount++;
}
}
if (wordCount > 0) {
System.out.println(letter + "=" + wordCount);
wordCount = 0;
}
}
}count occurrences of character in string java 8
String someString = "elephant";
long count = someString.chars().filter(ch -> ch == 'e').count();
assertEquals(2, count);
long count2 = someString.codePoints().filter(ch -> ch == 'e').count();
assertEquals(2, count2);number of occurence string in java
public class StringNumberOfOccurenceLetter {
private static int countOccurences(String word, char character){
int count = 0;
for (int i = 0; i < word.length() ; i++) {
if (word.charAt(i)==character){
count++;
}
}
return count;
}
public static void main(String[] args) {
int count = countOccurences("dddssad", 'a');
