10.4 Designing a MyPoint class
Subject:
Code:
import java.util.Scanner;
class MyPoint{
private double x;
private double y;
public MyPoint() {
}
public MyPoint(double x,double y) {
this.x=x;
this.y=y;
}
public double distance(MyPoint secondPoint) {
return distance(this,secondPoint);
}
public static double distance(MyPoint p1,MyPoint p2) {
return Math.sqrt((p1.x-p2.x)*(p1.x-p2.x)+(p1.y-p2.y)*(p1.y-p2.y));
}
public double getX() {
return x;
}
public double getY() {
return y;
}
}
public class Exercise10_04 {
public static void main(String[] args) {
Scanner in= new Scanner(System.in);
MyPoint p1=new MyPoint();
MyPoint p2= new MyPoint(10.0,30.5);
System.out.println(p1.distance(p2));
System.out.println(MyPoint.distance(p1,p2));
}
