Hi Friend,

Try the following code:

import java.util.*;
public class IDNumber{
    public static String removeCharAt(String s, int pos) {
   StringBuffer buf = new StringBuffer( s.length() - 1 );
   buf.append( s.substring(0,pos) ).append( s.substring(pos+1) );
   return buf.toString();
}
public static void main(String[] args){
Scanner input = new Scanner(System.in);
StringBuffer buffer=new StringBuffer();
System.out.print("Enter Number:");
String st = input.nextLine();
String [] arr = new String[st.length()];
int sum = 0;
for (int i = 0; i < st.length(); i++){
arr[i] = st.substring(i,i+1);
buffer.append(arr[i]);
buffer.append("+");
sum = sum + Integer.parseInt(arr[i]);
}
int len=buffer.length();
System.out.println(len);
String result=removeCharAt(buffer.toString(),19);
System.out.print(result+"="+sum);
}
}

Thanks

Hi, can you recommend a simple one using int array ? Because i cant understand the previous 1.Sorry and thanks a lot.
