Chapter 19, Problem 19.11PE

Program Plan Intro

ComplexMatrix

Program Plan:

• Include a class name named “Exercise19_11”.
  • Declare util package.
  • Declare main method.
    • Define the matrices “arr1” and “arr2” using the class “Complex”.
    • Using “for” loop, generate values into arrays.
    • Add and multiply the matrices and multiply the matrices using “GenericMatrix” class.
  • Define the method named “removeDuplicates”.
    • Define the object “ans” for “ArrayList” class.
    • Using condition, check the duplicate values in arrays and return the result.
• Include a class name named “ComplexMatrix” which extends the “GenericMatrix”.
  • Define the method named “add()” which add two matrices and return the resultant value.
  • Define the method named “multiply()” which multiplies two matrices and return the resultant value.
  • Define the method named “zero()” which fills “0” to matrices.
• Include an abstract class name named “GenericMatrix”.
  • Declare the methods “add”, “multiply”, and “zero” with generic object “E”.
  • Define all the methods with their arguments.
  • Define “printResult()” method to print the resultant values on screen.
• Include a class name named “Complex”.
  • Declare package.
  • Declare main method.
  • Declare double variables “a” and “b”.
  • Declare Constructors that creates a complex object for number 0.
  • Declare a constructor that creates a complex object with 0 for b.
  • Declare a constructor that creates a complex object with specified a and b.
  • Declare a method to return real part of complex number.
  • Declare a method to return imaginary part of complex number.
  • Declare a method to add a complex number to this complex number.
  • Create a method to subtract a complex number from this complex number.
  • Create a method to multiply a complex number by this complex number.
  • Create a method to divide a complex number by this complex number.
  • Create a method that returns the absolute value of this complex number.
  • The protected clone method defined in the Object class is overridden, its accessibility is strengthened.
  • Close the main method.
