// as well as a count of letters
import java.util.*;
public class DebugSeven4
{
public static void main(String[] args)
{
Scanner kb = new Scanner(System.in);
String aString ;
int numLetters = 0;
int stringLength;
System.out.println("Enter a String. Include");
System.out.println("some uppercase letters, lowercase");
System.out.print("letters, and numbers >> ");
aString = kb.nextLine();
stringLength = aString.length();
System.out.print("In all lowercase, the String is: ");
for(int i = 0; i <= stringLength; i++)
{
char ch = Character.toLowerCase(aStringcharAt(i));
System.out.print(ch);
if(!Character.isLetter(ch))
numLetters++;
}
System.out.println();
System.out.println
("The number of CHARACTERS in the string is " + stringLength);

The program must pass the test case when uploaded to Hypergrade. Chapter 9. PC #2. Word Counter (page 608) 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. Test Case 1 Please enter a string or type QUIT to exit:\nHello World!ENTERThere are 2 words in that string.\nPlease enter a string or type QUIT to exit:\nI have a dream.ENTERThere are 4 words in that string.\nPlease enter a string or type QUIT to exit:\nJava is great.ENTERThere are 3 words in that string.\nPlease enter a string or type QUIT to exit:\nquitENTERarrow_forward16arrow_forward
