Java String Exercises: Return the sum of the digits present in the given string
Java String: Exercise-95 with Solution
Write a Java program to return the sum of the digits present in the given string. If there is no digits the sum return is 0.
Sample Solution:
Java Code:
import java.util.*;
public class Main
{
public int sumOfDigits(String stng)
{
int l = stng.length();
int sum = 0;
for (int i = 0; i < l; i++)
{
if (Character.isDigit(stng.charAt(i)))
{
String tmp = stng.substring(i,i+1);
sum += Integer.parseInt(tmp);
}
}
return sum;
}
public static void main (String[] args)
{
Main m= new Main();
String str1 = "ab5c2d4ef12s";
System.out.println("The given string is: "+str1);
System.out.println("The sum of the digits in the string is: "+m.sumOfDigits(str1));
}
}
Sample Output:
The given string is: ab5c2d4ef12s The sum of the digits in the string is: 14
