next() problem
I've been trying to figure out how to repeat this loop of printingvout the integers and skipping the string with a .next Line but I can get it to repeat even though it's in a while loop?

I mean, the simpler approach is nextInt() followed by next(). What did they expect with nextLine()?
I get an noSuchelementexception when I run it with that
With your input that shouldn't be the case. Show the code
You need to stop pics and paste code
Same for the input
We can't try it otherwise, as you should not have needed to be told
import java.util.;
import java.io.;
public class Mc {
public static void main(String[] args) throws FileNotFoundException {
Scanner input = new Scanner(new File("money.txt"));
System.out.println(countMoney(input));
}
public static int countMoney(Scanner input){
int num = 0;
while(input.hasNextLine()){
num = input.nextInt();
input.next();
}
return num;
}
}
Ah, it was supposed to be hasNext(), not hasNextLine()
oh
alright it kinda worked? it printed out the last integer but im trying to print out all the integers in the text
Then rather than assign the number, print it
It worked
Thank you
