Answer to Question #33306 in Java | JSP | JSF for Roy

Question

Implement a class Moth that models a moth flying across a straight line. The moth has a position, 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. Supply a conductor
public Moth(double initialPosition)
and methods
public void moveToLight(double lightPosition)
public double getPosition

Answer 1

public class Test
{
publicstatic void main(String[] args)
{
Mothmoth1=new Moth(1.0);
Mothmoth2=new Moth(3.0);

doublelightPos=2.0;

moth1.moveToLight(lightPos);
moth2.moveToLight(lightPos);

System.out.println("moth1"+moth1.getPosition());
System.out.println("moth2"+moth2.getPosition());
}
}

public class Moth
{
privatedouble position;

publicMoth(double initialPosition)
{
this.position= initialPosition;
}

publicvoid moveToLight(double lightPosition)
{
position=(lightPosition+position)/2;
}

publicdouble getPosition()
{
returnposition;
}
}
