BONUS PROJECT
Task 1] Create the class Complex that includes the following properties, constructors and methods.
Most of the methods were previously created in a solved project uploaded to the D2L portal of the
course.
? Complex
-real: double
-imag: double
+Complex()
+Complex(real: double, imag: double)
+getReal(): double
+getImag(): double
+setReal(real: double): void
+setImag(imag: double): void
+getAngle(): double
+getAngle2(): double
+getRadius(): double
+pow(): double
+conjugate(): Complex
+add(in: Complex): Complex
+subtract(in: Complex): Complex
+multiply(in: Complex): Complex
+divide(in: Complex): Complex
+printComplex(): void
+nextComplex(): Complex
+equals(o: Object): boolean
+toSting(): String
The implementation of the class Complex was provided as a lab.

Task 2] Create the class Matrix. The class properties, constructors, and methods are described below. Be
aware that this class does not extend the class Complex. There is a relationship of composition between
the two classes. The created 2D array is always square.
? Matrix
-value: Complex[][]
+Matrix()
+Matrix(n: int)
+getDim(): int
+getReal(): double[][]
+getImag(): double[][]
+getCol(k: int) throws IllegalArgumentException: Complex[]
+getRow(k: int) throws IllegalArgumentException: Complex[]
+getDiag(): Complex[]
+pow(): double
+randomMatrix(size: int): Matrix
+add(m: Matrix): Matrix
+display(): void

(1) A constructor that takes no argument. The constructor creates a 3-by-3 Complex 2D array
referenced by the variable value.
(2) A constructor that takes an integer. The constructor creates an n-by-n Complex 2D array
referenced by the variable value.
(3) This method returns the number of rows in the array referenced by the variable value. Note that
the number of rows is equal to the number of columns.
(4) This method returns the real part of this object as 2D array of type double.
(5) This method returns the imaginary part of this object as 2D array of type double.
(6) This method returns the column of the 2D array referenced by value and whose index is taken as
an argument. The method throws an exception if the taken index k is out of bounds. The method
returns a Complex one-dimensional array.
(7) This method returns the row of the 2D array referenced by value and whose index is taken as an
argument. The method throws an exception if the taken index k is out of bounds. The method
returns a Complex one-dimensional array.
(8) This method returns the diagonal elements of the 2D array referenced by value. The method
returns a Complex one-dimensional array.
(9) This method returns the power sum of the elements of the Complex two-dimensional array
referenced by the variable value of this object.

(10)
This method returns a reference to a random size-by-size Complex two-dimensional
array. Use the method nextComplex() from the class Complex to generate a Complex object
whose real and imaginary parts are drawn randomly.
(11)
This method returns a reference to an object from the class Matrix. The returned
reference variable refers to the two-dimensional array resulting from adding this object to the
taken object.
(12)
This method displays this Matrix object. The format is of your choice.
The following is a Test class of the project.
