Write code which takes a sentence as an input from the user and then prints the length of the first word in that sentence. Hint: think about how you know where the first word ends - you may assume that the sentence contains more than one word.
Input a code in the following:
/* Lesson 3 Coding Activity Question 4 */
import java. util. Scanner;
public class U2_L3_Activity_Four{
public static void main(String[] args){
/* Write your code here */
}
}

Following are the java code to the given question:

import java.util.Scanner;//import package

public class U2_L3_Activity_Four //defining a class U2_L3_Activity_Four

{

  public static void main(String[] args) //defining main method

  {

      String s;//defining String variable

      int x,v=0;//dclaring integer variable x,v

      Scanner obx = new Scanner(System.in);//creating Scanner class Object

      System.out.println("Enter a sentence.");//print message

      s = obx.nextLine();//input string value

      for (x = 0; x < s.length(); x++)//defining loop to count string length

      {

          char c = s.charAt(x);//defining char variable that hold char value

          if (c != ' ')//defining if that check space value

          {

              v++;

          }

      }

      System.out.println("The first word is " + v +" letters long");//print length of first word

  }

}

Output:

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!
