Greetings,

我正试图从每一点到下文所述其他每一点,找到 Java的所有X、Y轴心。我正在视窗上使用Eclipse。非常赞赏对这一问题的帮助。

三个例子:(1.0、2.0)(2.0、2.0)(3.0、4.0)

所有奶制品从每一方到每一方:

Output:

(1.0 ,2.0) (2.0, 2.0)
(1.0, 2.0) (3.0, 4.0)

(2.0, 2.0) (1.0, 2.0)
(2.0, 2.0) (3.0, 4.0)

(3.0, 4.0) (1.0, 2.0)
(3.0, 4.0) (2.0, 2.0)

Thanks,
Paul

Answer 1

只好两次列入清单,但排除了相同的情况:

List<Point> points = new ArrayList<Point>();
points.add(new Point(1, 2));
points.add(new Point(2, 2));
points.add(new Point(3, 4));
printCombinations(points);

public static void printCombinations(List<Point> points) {
    for (int i = 0; i < points.size(); i++) {
        for (int j = 0; j < points.size(); j++) {
            if (i != j)
                System.out.println(points.get(i) + ":" + points.get(j));
        }
    }
}

Answer 2

短 h:穿过所有点,穿透所有以下各点,在其他地方添加奶粉。
