3. public class MaxOccuranceOfChar{
4.    
5. public static String MaxOccuredChar(String str) {
6.  
7.         char[] array = str.toCharArray();
8.         int maxCount = 1;
9.         char maxChar = array[0];
10.  
11.   for(int i = 0, j = 0; i < str.length() - 1; i = j){
12.        int count = 1;
13.    while (++j < str.length() && array[i] == array[j]) {
14.           count++;
15.         }
16.  
17.   if (count > maxCount) {
18.      maxCount = count;
19.      maxChar = array[i];
20.  }
21.  
22.   }
23.  
24.         return (maxChar + " = " + maxCount);
25.  }
26. 
    
27.  public static void main(String[] args) {
28.   
29.   String str1=MaxOccuredChar("instanceofjava");
30.   System.out.println(str1);
31.  
32.   String str2=MaxOccuredChar("aaaabbbccc");
33.   System.out.println(str2);
34.  
35.   String str3=MaxOccuredChar("ssssiiinnn");
36.   System.out.println(str3);
37.  
38.   String str4=MaxOccuredChar("jaaaavvvvvvvvaaaaaaaaaa");
39.   System.out.println(str4);
40.  
41. }
42. 
    
43. }

Output:

1. i = 1
2. a = 4
3. s = 4
4. a = 10
