Print Number of occurrences of each character from a string.

 Print the Number of occurrences of character form a string, we have many solution to solve this.

Here I posted a simple way I used to print number of occurrences of each character. 

private static void occurrenceOfChar(String input) {
    int length = input.length();
    char[] inputArray = input.toCharArray();
    while(input.length() > 0){
        input = input.replace(inputArray[0]+"", "");
        System.out.println(inputArray[0] +" Occurrences is " + (length - input.length()));
        inputArray = input.toCharArray();
        length = input.length();
    }
}

Input : Helloworld

Output : 

H Occurrences is 1
e Occurrences is 1
l Occurrences is 3
o Occurrences is 2
W Occurrences is 1
r Occurrences is 1
d Occurrences is 1
