Question

Lab 2​​ ​CISC 1115

Start a new Java program. It should begin by printing, as part of the output (in addition to the comment at the beginning of your code, a header for the lab (or homework) that looks like the following:

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

Your name​ Due Date

CISC 1115 MY11 ​ Lab2

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

Write a program that will read a double from the keyboard, which represents a dollar and cents amount, such as 7325.67, and prints out:

7325.67 is 7 thousand 3 hundred 2 tens 5 dollars and 67 cents

Input of 123 54 would print

123.54 is 0 thousand 1 hundred 2 tens 3 dollars and 54 cents

Or, for input of 100.00 the program will print

100.0 is 0 thousand 1 hundred 0 tens 0 dollars and 0 cents

Input of 12.54 would print

12.54 is 0 thousand 0 hundred 1 tens 2 dollars and 54 cents

Another example,

0.54 is 0 thousand 0 hundred 0 tens 0 dollars and 54 cents

One way to do this is to use casting, integer division and the mod operator (%) as we will discuss in the lecture but feel free to go your own way.

One set of code should work for any amount read in as a double. Assume the input amount is never greater than 99999.99

Print the code and run a number of examples like those above.

Having trouble understanding this, please help. Thank you!!

Answer 1

ConvertDollar.java

import java.util.Scanner;

public class ConvertDollar {

   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       System.out.println("Enter a dollar and cents amount:");
       double n = scan.nextDouble();
       int amount = (int)(n * 100);
       int thousand = amount/100000;
       amount = amount % 100000;
       int hundred = amount/10000;
       amount = amount % 10000;
       int tens = amount/1000;
       amount = amount % 1000;
       int dollars = amount/100;
       amount = amount % 100;
       int cents = amount;
       System.out.println(n+" is "+thousand+" thousand "+hundred+" hundred "+tens+" tens "+dollars+" dollars and "+cents+" cents");
   }

}

Output:

Enter a dollar and cents amount:
7325.67
7325.67 is 7 thousand 3 hundred 2 tens 5 dollars and 67 cents
