counting repeated characters in a string in java
String s="mmababctamantlslwgikl";
int distinct = 0 ;
while(s.length()>0){
for (int j = 0; j < s.length(); j++) {
if(s.charAt(0)==s.charAt(j))
{
distinct++;
}
}
System.out.println(s.charAt(0)+"--"+distinct);
String d=String.valueOf(s.charAt(0)).trim();
s=s.replaceAll(d,"");
distinct = 0;
}java, how to find the most repeated character
private static String findMaxChar(String str) {
char[] array = str.toCharArray();
Set<Character> maxChars = new LinkedHashSet<Character>();
int maxCount = 1;
maxChars.add(array[0]);
for(int i = 0, j = 0; i < str.length() - 1; i = j){
int count = 1;
while (++j < str.length() && array[i] == array[j]) {
count++;
}
if (count > maxCount) {
maxCount = count;
maxChars.clear();
maxChars.add(array[i]);
} else if (count == maxCount) {
maxChars.add(array[i]);
}
}
return (maxChars + " = " + maxCount);
