java求两点距离

Posted 2023-03-22

点(5，5)，点(10，20)要求写出点PONIT类
要求2点的距离

参考技术A public class Point

private double x;
private double y;

public Point(double x, double y)
this.x = x;
this.y = y;


public double getDistance(Point p)
double _x = Math.abs(this.x - p.x);
double _y = Math.abs(this.y - p.y);
return Math.sqrt(_x*_x+_y*_y);

public static void main(String[] args)
Point p1 = new Point(5, 5);
Point p2 = new Point(10, 10);
System.out.println(p2.getDistance(p1));

追问

能不能说一下每一步是什么意思啊，尤其是double _x = Math.abs(this.x - p.x);
看不懂耶
