Question

Implement a class Moth that models a moth flying along a straight line. The moth has a position which is the distance from a fixed origin. When the moth moves toward a point of light its new position is halfway between its old position and the position of the light source.

public Moth(double initialPosition)
public void moveToLight(double lightPosition)
public double getPosition()

Answer 1

All Class are Implemented in Java and executed

import java.io.*;
import java.util.*;
class Moth
{
private double position;
public Moth(double initialPostion)
{
position = initialPostion;
}
public void moveToLight(double lightPosition)
{
position = (position + lightPosition);
}

public double getPosition()
{
return position;
}
}
public class MothTester
{
public static void main(String args[])
{
Scanner sc = new Scanner(System.in);
System.out.println("Enter Initial Position");
int n = sc.nextInt();
System.out.println("Enter New Position");
float b = sc.nextFloat();
Moth moth = new Moth(n);
System.out.println("Initial Position of the Moth =" +moth.getPosition());
moth.moveToLight(b);
System.out.println("New Position of Moth =" +moth.getPosition());
}
}
