Solution Review: Calculate Distance Between Points

import java.lang.Math; 
class Point {
  // Private fields
  private int x;
  private int y;
  // Default Constructor
  public Point() {
    x = 0;
    y = 0;
  }
  // Parameterized Constructor
  public Point(int x, int y) { 
    this.x = x;
    this.y = y;
  }
  // Distance from origin
  public double distance() {
    double distance = Math.sqrt(x*x + y*y);
    return distance;
  }
  // Distance from (x2, y2)
  public double distance(int x2, int y2) {
    double distance = Math.sqrt(((x2-x)*(x2-x))+((y2-y)*(y2-y)));
    return distance;
  }
}
class Demo {
  public static void main(String args[]) {
    Point p1 = new Point(5, 5);
    System.out.println(p1.distance());
    System.out.println(p1.distance(2, 1));
  }
