Problem Description
输入两点坐标(X1,Y1),(X2,Y2),计算并输出两点间的距离。
Input
输入数据有多组,每组占一行,由4个实数组成,分别表示x1,y1,x2,y2,数据之间用空格隔开。
Output
对于每组输入数据,输出一行,结果保留两位小数。

import java.util.Scanner;
public class Main{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
while (scanner.hasNext()) {
double a = scanner.nextDouble();
double b = scanner.nextDouble();
double c = scanner.nextDouble();
double d = scanner.nextDouble();
double x = Math.pow(a-c, 2);
double y = Math.pow(b-d, 2);
double z = Math.sqrt(x+y);
System.out.println(String.format("%.2f",z));
}
