Provided code:

// This is a 'helper' class for Lab09.

public class StringPlay
{
  
// Static method to count the words in the input String
public static int countWords( String phrase )
{

}
  
// Static method to change all letters in the input String to uppercase
public static StringBuilder changeToUppercase( String phrase )
{

}  

//Static method to find middle word of the input String
public static String findMiddleWord( String phrase )
{

}  

}  

----------------------------------------------------------------------------

// This is a test harness for Lab09.

import java.util.Scanner;

public class Lab09
{
public static void main( String[] args)
{
Scanner input = new Scanner( System.in );
String finish = "Finish";   
  
System.out.printf("%nEnter a phrase containing at least three words%nOr enter finish to stop" );
  
String newPhrase = input.nextLine();
  
// You need to change the control condition here
while( newPhrase != finish )
{
// Call static methods of class StringPlay
System.out.printf("Your phrase contains %d words.", StringPlay.countWords( newPhrase ) );
System.out.printf("%nYour phrase with all letters in uppercase: %s",
StringPlay.changeToUppercase( newPhrase ) );
System.out.printf("%nThe middle word of your phrase is: %S%n%n",

Provided Resources 1. 2. 3. 4. Lab 09 Instructions, including requirements A test harness for your code (Lab09.java) A framework for StringPlay.java (three static methods need to be added) Sample output Requirements a) Add the necessary code to StringPlay.java: Method countWords 1. Receives a String value containing the user-input phrase passed from Lab09.java 2. Separates the phrase into individual words 3. Returns an int value containing a count of the individual words in the phrase Method changeToUppercase 1. Receives a String value containing the user-input phrase passed from Lab09.java 2. Declares a StringBuilder object 3. Separated the phrase into individual words, storing those words in an array of String type 4. Beginning with the first entry in the array, appends each word with all letters changed to uppercase (and a following space) to the StringBuilder object 5. Returns the StringBuilder object Method findMiddleWord 1. Receives a String value containing the user-input phrase passed from Lab09.java 2. Determines the number of words in the String 3. Finds the 'middle' word 4. Returns the String representing the middle or center word in the String
