Money class Java assignment.Please include lots of comments as I am fairly new at coding.

here is the Testing code that checks the functionality of the code:

package assign2;

import static org.junit.Assert.*;

import org.junit.Test;

public class MoneyTest {

@Test

public void testMonwy1() {

Money moneyObj = new Money(7, 33);

assertEquals ("$7.33", moneyObj.toString());

moneyObj = new Money (3, 55);

assertEquals ("$3.55", moneyObj.toString ());

}

@Test

public void testMoney2() {

Money moneyObj = new Money(7, 33);

Money moneyObj2 = new Money (moneyObj);

assertEquals ("$7.33", moneyObj2.toString());

moneyObj2 = new Money (new Money (10, 10));

assertEquals ("$10.10", moneyObj2.toString());

}

@Test

public void testToString() {

assertEquals ("$7.00", moneyObj.toString());

moneyObj = new Money(0, 7);

assertEquals ("$0.07", moneyObj.toString());

}

@Test

}

@Test

}
