Java：float [] []点

Question

我正在使用开源程序，但我不明白应该如何编写这个类。

间

public Room(float[][] points)
Creates a room from its name and the given coordinates.

我猜这有点像

Room Parallelogram_Room = new Room{{0f,0f},{0f,400f},{625f,400f},{625f,400f},{625f,0f},{0f,0f}};

但它会出错，或者

Room Parallelogram_Room = new Room([0f][0f]);

但仍然出错。

拜托，我被卡住了！

Answer 1

你弄乱了语法。用括号包裹数组。

为了更清楚，创建数组然后将其传递给构造函数。

float[][] points = {{0f,0f},{0f,400f},{625f,400f},{625f,400f},{625f,0f},{0f,0f}};
Room Parallelogram_Room = new Room(points);

Answer 2

使用Room room = new Room(new float[][] { {3, 4}, {4, 5}, {4, 6} });
