Default help with a java script

im trying to fix my java script to count the dots. here is my code if any one can help. i had it set up to count spaces but cant figure out the dots lol
import java.util.Scanner;
public class Assign5_blanton
{
public static void main (String[] args)
{
String phrase; // a string of characters
int countdots; // the number of dots
//Initialize input
Scanner scan = new Scanner(System.in);

// Print a program header
System.out.println ();
System.out.println ("Character Counter");
System.out.println ();

// Read in a string
System.out.print ("Enter dots: ");
phrase = scan.nextLine();


// Initialize counts
countdots = 0;

// a for loop to go through the string character by character

for(int i=0; i < phrase.length(); i++)
{
if(phrase.charAt(i) == ' ')
{
countdots++;
}

}

// Print the results
System.out.println();
System.out.println ("Number of dots: " + countdots);
System.out.println ();
//Close input
scan.close();
}
}

You need to understand the difference between Java and JavaScript, this forum is for the latter.

That being said there are two ways to attack this problem (maybe more...). One is to loop through the string and count the dots (by comparing to '.'), the other is to remove all non-dots (possibly with a regular expression) and then to get the length of the remaining string.
