Question

Write code which takes a sentence as an input from the user and then prints the length of the first word in that sentence.

Answer 1

import java.util.Scanner;

public class U2_L3_Activity_Four {

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       System.out.println("Enter a sentence.");

       String sent = scan.nextLine();

       int count = 0;

       for (int i = 0; i < sent.length(); i++){

           char c = sent.charAt(i);

           if (c != ' '){

               count++;

       }

           else{

               break;

           }

       

   }

       System.out.println("The first word is " + count +" letters long");

   

   }

}

We check to see when the first space occurs in our string and we add one to our count variable for every letter before that. I hope this helps!
