Count number of digits in string using scanner

[Eranga]

I believe he meant Indent! haha

Yes it's. Sorry about the misspell.

Indent means, leave proper space in each line of the code.

Read the following document just after finish this.

Java Style Guide: Indentation

What do you mean by count the number of digits? do you mean the count the characters in the string?

[Eranga]

Oh duh, I'm sorry!

What you mean by that?

Seems to me it's like that. Or may be he wants to count numbers only, not the letters. Anyway, OP has to clear up us on that.

That's the different thing pal. I just ask you to do it point out the error is.

First you get the user input and seem that you tried to count the number of digit in a different method. So you have to call the relevant method with the correct parameter. That method return value print to the console. That what you've to do basically.

Yes, so after the user inputs a string, I want it to be passed into the method NumberOfDigits(). but i dont know how.

I already have it with a defined number but i get confused when using scanner.

import java.util.Scanner;

class NumberOfDigits
{
public static void main(String args[])
{
System.out.println("The Number Of Digits Is  " + NumberOfDigits( -23457));
}
public static int NumberOfDigits(int n)
{
if(n<0) n = -n;
int c = 1;
while(n > 9)
{
c++;
n = n/10;
}
return c;
}
}

I just meant that I should have known it was a misspell. i was apologizing for the dumb question.

I want it to count the characters yes, as in there are 4 digits in "4532"

[justin1980]

you can use the string.length() to count the characters like.

Scanner in = new Scanner(System.in);
System.out.print("Please enter a Number!");
String a = in.nextLine();

System.out.print("The Number Of Digits Is " + a.length());

[justin1980]

If there are spaces though, i think that string.length() will count spaces.

Okay, what's the logic you've in your mind. What's the way you think of.

Give a try lol.

[wendysbiggy]

you can use the string.length() to count the characters like.

Scanner in = new Scanner(System.in);
System.out.print("Please enter a Number!");
String a = in.nextLine();

System.out.print("The Number Of Digits Is " + a.length());

This makes much more sense to me. Thank you. I think the problem was that i should have rewrote a whole new class when using it with scanner and start fresh. Thank you both a lot for help, i learned something.

Yes, length() method counts everything on the specified string.

I prefer if you can guide our OP rather than just giving him a code. :)

Ok, sorry I was just trying to help.

Yep, I know that. And don't worry, I'm not discourage you. But if anyone learn a lot from you, that's the your gain right. If you just give a code most the people not learns things from that, and I hope our OP is not like that. :)

What does "OP" mean? I am new to forums so that might sound dumb.
