Java实现控制台输出两点间距离

package com.swift;import java.util.Scanner;public class PToP {  public static void main(String[] args) {    Scanner scan=new Scanner(System.in);    System.out.println("请输入第一个点的坐标值x1");    Double x1=Double.parseDouble(scan.nextLine());    System.out.println("请输入第一个点的坐标值y1");    Double y1=Double.parseDouble(scan.nextLine());    System.out.println("请输入第二个点的坐标值x2");    Double x2=Double.parseDouble(scan.nextLine());    System.out.println("请输入第二个点的坐标值y2");    Double y2=Double.parseDouble(scan.nextLine());    Double distance=Math.pow((Math.pow((x2-x1),2)+Math.pow((y2-y1),2)),0.5);    System.out.println("两个点之间的距离是："+distance);  }}
