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. Other notes: UML diagram: https://ufile.io/gtxzjcwf (click the link to see image) The arrow with an arrowhead resembling a triangle signifies that there exists an "is a" relationship between the two classes. The class pointed by the head is the superclass and the other end will be the sub-class. The other arrow signifies that the classes pointed by the arrow will be used by the other class at the other end.
