Function returning a value - 2 - Practice Exercises Java

Exercise 5.4:

Function returning a value - 2

Objetive:

Create a program whose Main must be like this:

public static void Main()
{
__Console.WriteLine("\"Hello, how are you\" contains {0} spaces", ____CountSpaces("Hello, how are you") );
}

CountSpaces is a function that you must define and that will be called from inside Main.

As you can see in the example, it must accept an string as a parameter, and it must return an integer number (the amount of spaces in that string).

public class Main
{
	public static int CountSpaces(String text)
	{
		int countSpaces = 0;
		String letter;
		for (int i = 0; i < text.length(); i++)
		{
			letter = text.substring(i, i + 1);
			if (letter.equals(" "))
			{
				countSpaces++;
			}
		}
		return countSpaces;
	}

	public static void main(String[] args)
	{
		System.out.printf("\"Hello, how are you\" contains %1$s spaces" + "\r\n", CountSpaces("Hello, how are you"));
	}
}
