 public class HelloWorld{


     public static void main(String []args){

            String string1 = "Hello World"; 

            

        int count;  

          

        char string[] = string1.toCharArray();  

          

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

            count = 1;  

            for(int j = i+1; j <string.length; j++) {  

                if(string[i] == string[j] && string[i] != ' ') {  

                    count++;  

                    string[j] = '0';  

                }  

            }  

            if(count > 1 && string[i] !='0') { 

                System.out.println(string[i]+":-"+count);  

            }else if (string[i]!='0'&& string[i]!=' '){
