how to find how much a character was repeated in a string java code example

Example 1: counting repeated characters in a string in java

void Findrepeter(){
    String s="mmababctamantlslmag";
    int distinct = 0 ;

    for (int i = 0; i < s.length(); i++) {

        for (int j = 0; j < s.length(); j++) {

            if(s.charAt(i)==s.charAt(j))
            {
                distinct++;

            }
        }   
        System.out.println(s.charAt(i)+"--"+distinct);
        String d=String.valueOf(s.charAt(i)).trim();
        s=s.replaceAll(d,"");
        distinct = 0;

    }

}

Example 2: 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);
}
