Write a method that accepts a String object as an argument and returns the number of

words it contains. For instance, if the argument is “Four score and seven years ago” the

method should return the number 6. Demonstrate the method in a program that asks the

user to input a string and then passes it to the method. The number of words in the string

should be displayed on the screen.

Solution

WordCountTest.java

import java.util.Scanner;

public class WordCountTest {

  
   public static void main(String[] args) {
       Scanner in = new Scanner(System.in);
       System.out.println(\"Enter the string :\");
       String str = in.nextLine();
       int count = wordCount(str);
       System.out.println(\"Word Count is \"+count);
      
}
public static int wordCount(String str){
   String words[] = str.split(\"\\\\s+\");
   return words.length;
}

}

Output:
