java编写Point类，要求： 具有属性：点的坐标（二维或三维） 具有方法：输出X坐标最大的点的坐标。 输出点关于原点的对称点。 分别输出两点间距离最近和最远的距离

好的，根据您的要求，我将扮演CSDN开发的C知道，回答您的问题。关于您的第一个问题，以下是Java编写Point类的代码：

public class Point {
    private double x;
    private double y;
    private double z;

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

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

    public double getX() {
        return x;
    }

    public double getY() {
        return y;
    }

    public double getZ() {
        return z;
    }

    public Point getMaxXPoint(Point[] points) {
        Point maxXPoint = points[0];
        for (int i = 1; i < points.length; i++) {
            if (points[i].getX() > maxXPoint.getX()) {
                maxXPoint = points[i];
            }
        }
        return maxXPoint;
    }

    public Point getSymmetricPoint() {
        double newX = -x;
        double newY = -y;
        double newZ = -z;
        return new Point(newX, newY, newZ);
    }

    public double getDistance(Point other) {
        double dx = x - other.getX();
        double dy = y - other.getY();
        double dz = z - other.getZ();
        return Math.sqrt(dx * dx + dy * dy + dz * dz);
    }

    public double[] getMinMaxDistance(Point[] points) {
        double minDistance = Double.MAX_VALUE;
        double maxDistance = Double.MIN_VALUE;
        for (int i = 0; i < points.length; i++) {
            double distance = getDistance(points[i]);
            if (distance < minDistance) {
                minDistance = distance;
            }
            if (distance > maxDistance) {
                maxDistance = distance;
            }
        }
        return new double[]{minDistance, maxDistance};
    }
}

以上代码实现了一个Point类，具有二维或三维坐标属性，以及输出X坐标最大的点的坐标、输出点关于原点的对称点、分别输出两点间距离最近和最远的距离的方法。如果您有任何问题，请随时问我。
