you could first get the length of the whole string and use a for loop to to go down the word and if charAt(i) == " " then increase a count and return count.

or you could assume that, since stuff like this can in a lot of ways be usefull, it has been implemented in Java already.
just go and take a look at what StringTokenizer is all about.
I'm quite sure it 'll help you do everything you want (except for making a cup of coffee when it's done :P )

public class SpaceCount {
	public static void main(String[] args) {
		String s = "This is my car.";
		int count = 0;
		
		for (int i = 0; i < s.length(); i++) {
			if (s.charAt(i) == ' ') count++;
		}
		
		System.out.println(count);
	}
}

Looks good to me :) congrats

public class SpaceCount {
	public static void main(String[] args) {		
		String line = "This is my car.";
		String[] spaces = line.split(" ");
		System.out.println(spaces.length - 1);
	}
}

Both examples are O(n) efficient; this second example is just cleaner imo.
