Java运用构造方法，计算并输出两点间的距离

import java.util.Scanner;
public class javaTest {
    public static void main(String[] args) {
// TODO Auto-generated method stub
        double x1,y1,x2,y2;
        Scanner sc=new Scanner(System.in);
        while(sc.hasNext()) {
            x1=sc.nextDouble();
            y1=sc.nextDouble();
            x2=sc.nextDouble();
            y2=sc.nextDouble();
            Point p1=new Point(x1,y1);
            Point p2=new Point(x2,y2);
            double d=dist(p1, p2);
            System.out.printf("The distance is %.2f\n", d);
        }
        sc.close();
    }
    static double dist(Point p1,Point p2)
    {
        double s;
        double dx=Math.abs(p2.getX()-p1.getX()) ;
        double dy=Math.abs(p2.getY()-p1.getY());
        s=Math.sqrt(dx*dx+dy*dy);
        return s;
    }
}
class Point {
        public double x,y;
        public Point(double a,double b){
        x=a;
        y=b;
        }

        }

        this.x=x;
        }
