- char maxChar = 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;
- maxChar = array[i];
- }
- }
- return (maxChar + " = " + maxCount);
- }
- public static void main(String[] args) {
- String str1=MaxOccuredChar("instanceofjava");
- System.out.println(str1);
- String str2=MaxOccuredChar("aaaabbbccc");
- System.out.println(str2);
- String str3=MaxOccuredChar("ssssiiinnn");
