埦写一个埴段垥Segment该垥有两个变量：两个表埳点的对象成员方法有：埲算长埶、埴条着色埵。画出UML图。java代码

UML图：

_________________
|    Segment    |
|_______________|
| - point1: Point|
| - point2: Point|
|_______________|
| + Segment(Point, Point)|
| + getLength(): double|
| + setColor(Color): void|
|_______________|

Java代码：

import java.awt.Color;

public class Segment {
    private Point point1;
    private Point point2;
    
    public Segment(Point point1, Point point2) {
        this.point1 = point1;
        this.point2 = point2;
    }
    
    public double getLength() {
        return point1.distance(point2);
    }
    
    public void setColor(Color color) {
        // set color of the segment
    }
}
