Question

2. Create ACCESSOR FUNCTIONS in JAVA
a) String moneyToString(int[] money); // Returns a nice looking string. Ex, "$6.25", "$0.21", "$4.01", "$2.00". MAKE SURE TO CONSIDER ALL EXAMPLES!
b) *String moneyToText(int[] money); // Returns the Money as words. Ex,{123,51} => "one hundred and twenty three dollars and fifty one cents." YOU MAY ASSUME money <$1000.

context:

this is what I have so far

package com.company;
import java.util.*;

public class Main
{
    public static void main(String[]args)
    {
        int money[] = createMoney(12, 34);
        int copy[] = copyMoney(money);
    }

    static int[] createMoney(int dollars, int cents)
    {
        if (cents>99)
        {
            int extraDollars=cents/100;     
            cents=cents%100;
            dollars+=extraDollars;
        }
        int money[] = { dollars, cents };
        return money;
    }
    static int[] copyMoney (int[]money)
    {
        int copy[]=new int[money.length];
        for (int i=0; i<money.length; i++)
        {
            copy[i]=money[i];
        }
        return copy;
    }
}

Answer 1

2.

a)

CODE

public static String moneyToString(int[] money) {

String result = "$";

if (money.length == 1) {

result += money[0];

} else if (money.length == 2) {

result += money[0];

if (money[1] != 0) {

result += "." + money[1];

}

} else {

result = "";

}

return result;

}

B)

CODE

public static String convert(final int n) {

String[] units = { "", "One", "Two", "Three", "Four",

"Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven", "Twelve",

"Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen",

"Eighteen", "Nineteen" };

String[] tens = {

"", // 0

"", // 1

"Twenty", // 2

"Thirty", // 3

"Forty", // 4

"Fifty", // 5

"Sixty", // 6

"Seventy", // 7

"Eighty", // 8

"Ninety" // 9

};

if (n < 20) {

return units[n];

}

if (n < 100) {

return tens[n / 10] + ((n % 10 != 0) ? " " : "") + units[n % 10];

}

return units[n / 100] + " Hundred" + ((n % 100 != 0) ? " " : "") + convert(n % 100);

}

public static String moneyToText(int[] money) {

String result = "";

if (money.length == 2) {

result += convert(money[0]) + " dollars and " + convert(money[1]) + " cents.";

} else if (money.length == 1) {

result += convert(money[0]) + " dollars.";

}

return result;

}
