Imagine the user types in a complete sentence, but we want to read only the first word and place it in the String variable word. What are the statements that will declare the Scanner object and read the value of word

import java.util.Scanner;

public class FirstWord {

   public static void main(String[] args) {

       //NOW YOU WANT TO COLLECT INPUTS FROM THE STUDENT OR USER

       //IMPORT THE SCANNER CLASS FIRST  outside your class

       // THEN YOU CREATE AN OBJECT OF THE SCANNER CLASS

       Scanner input = new Scanner(System.in);

       //CREATE A VARIABLE TO HOLD THE USER INPUT

       String text = input.nextLine();

       //The variable holder will be used to store characters from the for loop

       String holder="";

       //Create a for loop that loops through the user's input

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

           //As the loop increases, we get the character in the user's input and store them one by one in the variable holder

           holder+=text.charAt(i);

           if(text.charAt(i)==' '){

               //If the loop encounters a space, it means a complete word has been gotten from the user's input

               //Then the break below Breaks the loop, and the loop stops running

               break;

           }

       }

       System.out.println(holder);

}

Explanation:

text.length() returns the length of the sequence of characters present in length

text.charAt(a number) Returns the char value at the specified index. An index ranges from 0 to length() - 1. The first char value of the sequence is at index 0, the next at index 1, and so on, as for array indexing.

Create a for loop

How does a for loop work?

It collects a starting point, an end point and an increment respectivelyall these are passed in as arguments into the for loop

For example, the code above starts from 0, calculates the number of characters in the user's input and sets it as the end point, the loop runs from zero to the length of the text of the user...

Note: i++ in the loop is the increment, it means the loop increases by 1
