Question

对于构造函数，我要为用户分配每个变量的值。变量是：

int rows, cols;     // How big is the treasure map
Coord [] treasureLocations; // The locations of treasures

对于构造函数，我从每个变量的用户那里获取一个值。我已经找到了行和列，但我怎么能处理为treasureLocations获取用户输入的地方，它只能是一个输入值（例如0,1,2 ......）？ 请记住，我无法添加任何其他字段！ 提前谢谢！

public TreasureMap(){
      System.out.println("How many rows would you like to have? ");
      rows = kbd.nextInt();
      System.out.println("And how many columns would you like to have? ");
      cols = kbd.nextInt();
      System.out.println("Now enter the number of treasures you'd like to have: ");
      treasureLocations[] = kbd.nextInt();

}

Answer 1

像这样？

treasureLocations[] = new Coord [kbd.nextInt()];

Answer 2

在接受宝藏数量时声明数组。

public TreasureMap(){
      System.out.println("How many rows would you like to have? ");
      rows = kbd.nextInt();
      System.out.println("And how many columns would you like to have? ");
      cols = kbd.nextInt();
      System.out.println("Now enter the number of treasures you'd like to have: ");
      int[] treasureLocations = new int[kbd.nextInt()]; 
}

由于在接受所需元素数量之前已声明了数组，因此无法使用确切的元素数声明数组。

另一种解决方法是将该输入存储在另一个变量中，并循环后面的输入和输出序列，确切次数。

我应该如何将用户输入分配给数组对象？
