Question

Make a java program that facilitates addition, subtraction, multiplication, and division of mixed numbers but this time all of the inputs /outputs may involve fractions, mixed fractions, or a combination.

Points to consider:

MixedFraction class must override the operations (add, subtract, multiplyBy, divideBy) inherited from Fraction class to have a different implementation if the MixedFraction object will have a Fraction object as parameter in performing the required operation, On top of that, the inherited operations must also be overloaded to allow a MixedFraction object to accept other parameters such as a whole number or another MixedFraction object.
The toString method which is inherited must also be overridden by MixedFraction to have a more appropriate return value. Further formatting must also be considered such that if the result of the operation has a zero value for the whole part, the output should only show the fractional part (ex. 0 1/2 should be converted to 1/2), Also, a proper string value is to be returned if the result has a denominator of 1 (ex, 2 0/1 should be converted to 2),
toDouble method should also be overridden by MixedFraction.

The other arrow signifies that the classes pointed by the arrow will be used by the other class at the other end.
