Java program to add all numbers present in AlphaNumeric String

First Approach

package com.nt.logical;

import java.util.Scanner;

public class AddNoFromString 
{
 public static void main(String[] args) 
 {
  //getting the dynamic values from keyboard
  Scanner sc=new Scanner(System.in);
  System.out.println("Enter the String with number: ");
  String str=sc.nextLine();

  //logic for removing the alpha characters
  String[] s=str.split("[A-Za-z]");
  String ss="";

  //logic to remove white spaces
  for(int i=0;i<s.length;i++)
  {
   ss=ss+String.valueOf(s[i]);
  }
  
  //getting number from ss obj
  int num=Integer.valueOf(ss);
  int sum=0;
  
  //logic to add the numbers
  while(num>0)
  {
    sum=sum+num%10;
    num=num/10;
  }
  //printing the value after adding
  System.out.println("Value :"+sum);
 }
}

    }
  }
