I have the following code:

public class Money {
    private int dollar;
    private int cent;
    final static int MIN_CENT_VALUE = 0;
    final static int MAX_CENT_VALUE = 99;

    public Money() {
        this.dollar = 0;
        this.cent = 0;
    }

    public Money(int dollar, int cent) {
        this.dollar = dollar;
        if (cent >= MIN_CENT_VALUE && cent <= MAX_CENT_VALUE) {
            this.cent = cent;
        } else {
            cent = 0;
        }
    }

    public int getDollar() {
        return this.dollar;
    }

    public void setDollar(int dol) {
        this.dollar = dol;
    }

    public int getCent() {
        return this.cent;
    }

    public void setCent(int c) {
        if (c >= MIN_CENT_VALUE && c <= MAX_CENT_VALUE) {
            this.cent = c;
        }
    }

    public Money add(Money otherMoney) {
        Money m = new Money();
        m.dollar = dollar + otherMoney.dollar;
        m.cent = cent + otherMoney.cent;
        if (m.cent >= 100) {
            m.dollar++;
            m.cent -= 100;
        }

        return m;
    }

    public Money subtract(Money otherMoney) {
        Money m = new Money();
        m.dollar = dollar - otherMoney.dollar;
        m.cent = cent - otherMoney.cent;
        if (m.dollar < 0 || m.cent < 0) {
            return null;
        }
        return m;
    }

    public boolean equals(Money otherMoney) {
        return this == otherMoney;
    }

    public int compareTo(Money otherMoney) {
        if (this.dollar < otherMoney.dollar) {
            return this.dollar - otherMoney.dollar;
        } else if (this.dollar == otherMoney.dollar) {
            return 0;
        } else {
            return this.dollar- otherMoney.dollar;
        }
    }

    public String toString() {
        if (this.cent<10){
            return "$" + this.dollar + ".0" + this.cent;
        }
        return "$" + this.dollar + "." + this.cent;
    }

    public static Money max(Money[] m) {
        int max = m[0].dollar;
        int index = 0;
        for (int i = 0; i < m.length; i++) {
            if (max < m[i].dollar) {
                max = m[i].dollar;
                index = i;
            }
        }
        return m[index];
    }

    public static void selectionSort(Money arr[]) {
        int n = arr.length;

        for (int i = 0; i < n - 1; i++) {
            int min = i;
            for (int j = i + 1; j < n; j++)
                if (arr[j].dollar < arr[min].dollar)
                    min = j;

            // Swap the found minimum element with the first element
            Money temp = new Money();
            temp = arr[min];
            arr[min] = arr[i];
            arr[i] = temp;
        }
    }

    public static void printList(Money[] m, int i) // This method takes an array of object as parameter

    {
        for (Money mm : m){
            System.out.print(mm + "  ");
        }

        System.out.println();
    }
}

_________________________________________

for use with the following unchangleable driver program TestMoney

import java.util.*;
public class TestMoney
{
   public static void main(String[] args)
   {
      Random rnd = new Random(10);
      Money m1 = new Money(5,45);
      Money m2 = new Money(10,95);
      m1.setCent(101);
      Money sum = m1.add(m2);
      System.out.println(m1+" + "+m2+" is "+sum);
      Money diff = m1.subtract(m2);
      System.out.println(m1+" - "+m2+" is "+diff);
      diff = m2.subtract(m1);
      System.out.println(m2+" - "+m1+" is "+diff);
      System.out.println("equals method result: "+m1.equals(m2));
      System.out.println("compareTo method result: "+m1.compareTo(m2));

            
      Money[] list = new Money[15];
   // Generate 15 random Money objects
      for(int i=0;i<list.length;++i)
      {
         list[i] = new Money((int)(1+rnd.nextInt(30)),rnd.nextInt(100));
      }
   // print the list of Money objects, 10 per line
      System.out.println("Unsorted list");
      Money.printList(list,10);
   // Find the largest Money object
      System.out.println("The Max is "+Money.max(list));
  // Sort and print
      System.out.println("Sorted list");
      Money.selectionSort(list);
      Money.printList(list,10);
      }
}

 

its having 2 issues

1) compareTo method is incorrect (A method named compareTo which returns a positive int, a negative int, or zero
depending on order of this object and the otherMoney argument. )

2) 2 of the values (highlighted) are ordered incorrectly
