Question

1. Java . Create CONSTRUCTOR FUNCTIONS (Creating data according to your abstraction)

int[] createMoney(int dollars, int cents); // Given the number of dollars and cents, construct a Money abstraction. If given >99 cents, convert it to dollars. Abstraction is a process of hiding the implementation details from the user.
int[] copyMoney(int[] money); // Given a money, create a separate copy of it.

if needed, use Functions, Conditionals, Loops, and or Arrays

// Test.java

public class Test {

      // method to create an array containing 2 elements, first element holds the

      // amount in dollars, second element holds the remaining cents

      static int[] createMoney(int dollars, int cents) {

            // if cents >99, finding extra dollars by dividing cents by 100

            if (cents > 99) {

                  int extraDollars = cents / 100;

                  // removing extra dollars from cents

                  cents = cents % 100;

                  // adding extraDollars to dollars

                  dollars += extraDollars;

            }

            // creating a 2 element array with dollars being first element and cents

            // being second, returning this array

            int money[] = { dollars, cents };

            return money;

      }

      // returns the copy of the given money array

      static int[] copyMoney(int[] money) {

            // creating an array of same capacity

            int copy[] = new int[money.length];

            // copying all elements from money array to copy array

            for (int i = 0; i < money.length; i++) {

                  copy[i] = money[i];

            }

            return copy;

      }

      public static void main(String[] args) {

            // testing createMoney and copyMoney methods

            int money[] = createMoney(15, 125);

            int copy[] = copyMoney(money);

            System.out.println(money[0] + " dollars and " + money[1] + " cents");

            System.out.println("Copy: " + copy[0] + " dollars and " + copy[1]

                        + " cents");

      }

}

/*OUTPUT*/

16 dollars and 25 cents

Copy: 16 dollars and 25 cents
