Answer:
ArrayList a contains [2, 3, 3, 3, 4, 5, 3, 2, 1]
Explanation:
Given
The removeValue method
Required
The content of ArrayList a, after the method is called
From the question, we understand that arraylist a is:
The function fails when the value to be removed appear consecutively in the list.
4 appears in index 5 and 6 of the list. Only one of the 4's will be removed
So, the updated list will be: [2, 3, 3, 3, 4, 5, 3, 2, 1]
Answer:
Explanation:
The following code is written in Java, it creates the entire complex class as requested so that it works with the main method that has been provided in the question without having to change anything in the main method. Proof of output can be seen in the attached picture below
import java.util.Scanner;
class Test implements Cloneable{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter the first complex number: ");
double a = input.nextDouble();
double b = input.nextDouble();
Complex c1 = new Complex(a, b);
System.out.print("Enter the second complex number: ");
double c = input.nextDouble();
double d = input.nextDouble();
Complex c2 = new Complex(c, d);
System.out.println("(" + c1 + ")" + " + " + "(" + c2 + ")" + " = " + c1.add(c2));
System.out.println("(" + c1 + ")" + " - " + "(" + c2 + ")" + " = " + c1.subtract(c2));
System.out.println("(" + c1 + ")" + " * " + "(" + c2 + ")" + " = " + c1.multiply(c2));
System.out.println("(" + c1 + ")" + " / " + "(" + c2 + ")" + " = " + c1.divide(c2));
System.out.println("|" + c1 + "| = " + c1.abs());
Complex c3 = c1;
System.out.println(c1 == c3);
System.out.println(c3.getRealPart());
System.out.println(c3.getImaginaryPart());
}
}
