How would I get only the end result printed while also fixing the runtime error

I’m pretty new when it comes to coding in java (or coding in general), and I want the code below to print out only the end result (3), but it prints everything beforehand too, then once it reaches the end it gives me a runtime error

package programs;

public class practice2 
{
    public static void main(String [] args)
    {
        //create a program that counts spaces in a string
        String sentence = "test if this works";

        int count = 0;
        for(int i = 0; i <= sentence.length(); ++i)
        {
            String space = sentence.substring(i, i+1);
            if(space.equals(" "))
            {
                count = count + 1;
            }
            System.out.println(count);
        }
    }
}

Answer

To get the final output, you need to move the print statement outside of the for loop. As for the runtime error, change the looping condition to i < sentence.length() instead of i <= sentence.length() because indexing starts from 0 and end at length-1.
