用于在3D空间中查找直线和点之间距离的Java代码

import java.util.Scanner;

public class DistanceCalculator {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.println("请输入直线上两点的坐标（x1, y1, z1, x2, y2, z2）：");
        double x1 = scanner.nextDouble();
        double y1 = scanner.nextDouble();
        double z1 = scanner.nextDouble();
        double x2 = scanner.nextDouble();
        double y2 = scanner.nextDouble();
        double z2 = scanner.nextDouble();

        System.out.println("请输入点的坐标（x, y, z）：");
        double x = scanner.nextDouble();
        double y = scanner.nextDouble();
        double z = scanner.nextDouble();

        double distance = calculateDistance(x1, y1, z1, x2, y2, z2, x, y, z);
        System.out.println("点到直线的距离为：" + distance);
    }

    public static double calculateDistance(double x1, double y1, double z1, double x2, double y2, double z2, double x, double y, double z) {
        double A = (y2 - y1) * (z - z1) - (z2 - z1) * (y - y1);
        double B = (z2 - z1) * (x - x1) - (x2 - x1) * (z - z1);
        double C = (x2 - x1) * (y - y1) - (y2 - y1) * (x - x1);

        double distance = Math.abs(A * x + B * y + C * z + (A * x1 + B * y1 + C * z1)) / Math.sqrt(A * A + B * B + C * C);
