Can someone please explain how to count the digits in a string??For example:
1 2 3 4 = 10
I have this homework problem in which it has already set up part of the code and I just need to fill in the rest and I know I need to use Integer.parseInt(); I just dont know where:
import java.io.*;
import java.util.*;
public class EchoSum extends Echo
{
public EchoSum (String datafile) throws IOException
{
super(datafile);
}
// Prints the sum of each line.
public void processLine(String line){
//my code goes here!
Explanation / Answer
{
int sum=0;
for(int i=0;i<line.length();i++)
{
sum = sum + Integer.parseInt(line.substring(i, i+1));
}
System.out.println(sum);
