Explanation of Solution
Modified definition of the class “SpeciesFirstTry” in Listing 5.3:
The modified definition of the class “SpeciesFirstTry” after assigning a number for each species is given below:
//Import package
import java.util.Scanner;
//Define a class "SpeciesFirstTry"
public class SpeciesFirstTry
{
//Declare a string variable for species name
public String name;
//Declare an int variable for species number
public int number;
//Declare an int variable for population
public int population;
//Declare a double variable for species name
public double growthRate;
//Function definition for "readInput"
public void readInput()
{
//Create scanner object
Scanner keyboard = new Scanner(System.in);
//Read input for species name from user
System.out.println("What is the species' name?");
name = keyboard.nextLine();
//Read input for species number from user
System.out.println("What is the species' number?");
number = keyboard.nextInt();
//Read input for population from user
System.out.println("What is the population of the species?");
population = keyboard.nextInt();
//Read input for growth rate from user
System.out.println("Enter growth rate (% increase per year):");
growthRate = keyboard.nextDouble();
}
//Function definition for "writeOutput"
public void writeOutput()
{
//Display species name
System.out.println("Name = " + name);
//Display species number
System...

- Answer two JAVA OOP questions.arrow_forwardPlease answer Java OOP Questions.arrow_forward.NET Interactive Solving Sudoku using Grover's Algorithm We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…arrow_forward
