Question

Consider the Point class below. Add a method to the class named distanceToPoint. The method should accept a Point object as a parameter. It should return the distance between the point that receives the invocation, and the parameter.

Feel free to use Math.sqrt, and Math.pow.

public class Point {

  private double x;

  private double y;

  public void setX(int value) { x = value; }

  public double getX() { return x;}

  public void setY(int value) { y = value; }

  public double getY() { return y;}

// write your distanceTo method as if it is here

}

Explanation / Answer

Hi, Please find my code:

Please let me know in case of any issue:

public class Point {

private double x;
private double y;

public void setX(int value) { x = value; }
public double getX() { return x;}

public void setY(int value) { y = value; }
public double getY() { return y;}

// write your distanceTo method as if it is here
public double distanceToPoint(Point other){

// distancd: sqrt((x1-x2)^2 + (y1-y2)^2)
   double distance = Math.sqrt( Math.pow(x - other.x, 2) + Math.pow(y - other.y, 2) );
   return distance;
}
}
