Explanation of Solution
Program:
File name: “CountWords.java”
//Import necessary header files
import java.util.*;
//Define a class named CountWords
public class CountWords
{
//Define main method
public static void main(String[] args)
{
//Create an object for the Scanner class
Scanner in = new Scanner(System.in);
//Declare the variables
String str;
char ch;
int x;
int count = 0;
int length;
//Declare a Boolean variable and initialize the value
boolean previousCharWasPunc = false;
//Prompt the user to enter a String
System.out.print("Enter a string >> ");
str = in.nextLine();
//Read the length of the String
length = str.length();
//For loop is executed until x exceeds the string length
for(x = 0; x < length; x++)
{
ch = str.charAt(x);
/* If the words are separated by any combination of spaces,
periods, commas, semicolons, question marks,
exclamation points, or dashes*/
if(ch == ' ' || ch == '...

- For Java Write an application that counts the words in a String entered by a user. Words are separated by any combination of spaces, periods, commas, semicolons, question marks, exclamation points, or dashes. Figure 7-17 shows a typical execution.arrow_forwardWrite a Java application for Blizzy's car care Shop that shows a user a list of available services: oil change, tire rotation, battery check, or brake inspection. Allow the user to enter a string that corresponds to one of the options, and display the option and its price as R250, R220, R150, or R50, accordingly. Display an error message if the user enters an invalid item.arrow_forwardWrite a java application for Limpopo’s Car Care Shop that shows a user a list of available services: oil change, tire rotation, battery check, or brake inspection.

- Write a java application for an Auto Car shop that shows a user a list of available services: oil change, tire rotation, battery check, or brake inspection. Allow the user to enter a string that corresponds to one of the options, and display the option and its price as €9, €7, €5, or €3, accordingly. Display an error message if the user enters an invalid item.

For example, the three-letter words produced from the word “bathe” include “ate,” “bat,” “bet,” “tab,” “hat,” “the” and “tea.”arrow_forwardHere is the question and needs to be written in java: Write an application that accepts a word from a user and converts it to Pig Latin. If a word starts with a consonant, the Pig Latin version removes all consonants from the beginning of the word and places them at the end, followed by ay. For example, cricket becomes icketcray. If a word starts with a vowel, the Pig Latin version is the original word with ay added to the end. For example, apple becomes appleay. If y is the first letter in a word, it is treated as a consonant; otherwise, it is treated as a vowel. For example, young becomes oungyay, but system becomes ystemsay. For this program, assume that the user will enter only a single word consisting of all lowercase letters.arrow_forward

Reads a string from the standard input device and store it in a variable called inputStr.2. Find all the letter characters in inputStr and store them in another string variable called letterChars. Then, convert all the characters in letterChars to uppercase characters (i.e., capital letters).3. Display the contents of letterChars to the user using a message dialog box.For example, if the contents of inputStr is “q123Ab455c6d”, then the final contents of letterChars will be “QABCD”.arrow_forwardWrite a Java application with (comments) for Car Care Shop that shows a user a list of available services: oil change, tire rotation, battery check, or brake inspection.

The method checks the character at the specified index of the String parameter, and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character. Ex: The method calls below with the given arguments will return the following Strings: checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"arrow_forward
