Use java, you are to create a brand new base class called NSpaceCoordinate in a file called nspace/NSpaceCoordinate.java. It has the following requirements: 1. It must have a single private field, an ArrayList specialized (using the generics feature discussed in the lecture) to holding values of type double (actually, Double). 2. Provide a constructor that takes a double[] and sets up the ArrayList field to have those same values. 3. Provide a method called getNthCoordinate(int i). 4. Implement the Comparable...

A complex number is a number in the form a + bi, where a and b
are real numbers and i is sqrt( -1). The numbers a and b are known
as the real part and imaginary part of the complex number,
respectively.
You can perform addition, subtraction, multiplication, and division
for complex numbers using the following formulas:
a + bi + c + di = (a + c) + (b + d)i
a + bi - (c + di)...
