Question

Consider the following class hierarchy:
public final class Shape
{
private String mycolor:
public Shape(String mycolor)
{
this.tvpe = mvcolor:
}
public String getCoelor)
{
return mycolor:
}
}
public class Triangle extends Shape
{
public Triangle(String mycolor)
{
super(mycolor);
}
}
}
What is wrong with this class hierarchy definition? Justify your choice.
a) Nothing is wrong with the code.
b) There should be more subclasses of the Shape class than just Triangle.
c) There cannot be any subclasses of the Shape class.
d) It is not possible to use super in the Triangle constructor.

For this assignment you will be building on your Fraction class. However, the changes will be significant, so I would recommend starting from scratch and using your previous version as a resource when appropriate. For this assignment, we will correctly handle Fractions that are negative, improper (larger numerator than denominator), or whole numbers (denominator of 1). Your class should support the following operations on Fraction objects: Construction of a Fraction from two, one, or zero integer arguments. If two arguments, they are assumed to be the numerator and denominator, just one is assumed to be a whole number, and zero arguments creates a zero Fraction. Use default parameters so that you only need a single function to implement all three of these constructors.You should check to make sure that the denominator is not set to 0. The easiest way to do this is to use an assert statement: assert(inDenominator != 0); You can put this statement at the top of your constructor. Note…
