Question

1. Write a Java program to count all words in a string. User inputs a string sentence and your program should count the number of words in that string.

Test Data:
Input the string: The quick brown fox jumps over the lazy dog.
Expected Output:

Number of words in the string: 9

2. Write a class called ATMTransaction. This class has a variable balance and account number. It has three methods, checkBalance, deposit and withdraws along with constructors getters and setters and a toString. Write a program that creates an object of this class. I should be able to deposit and withdraw from my account number based on my balance, but I shouldn't be able to change my account number. Look for loopholes in your program, test it correctly, your balance cannot be negative.

I am close to completing the assignment. For the Word Count. It was supposed to count the words that it was supposed to type. But if you hit nothing, it was to type out a zero, nothing, not a " 1 ". This is what I have so far. My professor said that I am missing an if else statement.

Here is the Word Count ⤵

       Scanner input = new Scanner(System.in);

       System.out.println("Input the string: ");

       String phrase = input.nextLine();

//        if (phrase == "") {

//            System.out.println("Number of words in the string: 0");

//        }

//        else{

System.out.printf("Number of words in the string: " + phrase.split("").length);

       // }

   }

}

And the last thing is the ATM. I have everything, but my professor said I am missing a getter and a setter. And the toString. That it is missing to include the account number. There is no string account number for them, no private double balance and account number.

Here is the code for the ATM ⤵

Answer 1:

import java.util.Scanner;

public class WordCount {

   /**
   *
   * @param args
   * the command line arguments
   *
   */

   public static void main(String[] args) {

       Scanner input = new Scanner(System.in);

       System.out.println("Input the string: ");

       String phrase = input.nextLine();

       if (phrase.trim().length() == 0) {

           System.out.println("Number of words in the string: 0");

       }

       else {

           System.out.printf("Number of words in the string: " + phrase.split(" ").length);

       }

   }
