Creating arrays in java and initialising in constructor
提问by friendlycow
I need to create an array of objects (Cars) and then initialise the array to be of a required size (10) within a constructor. So far I have this:
我需要创建一个对象数组 (Cars)，然后在构造函数中将数组初始化为所需大小 (10)。到目前为止，我有这个：
public class Queue {
private Car [] car;
public Queue (Car [] car) {
Car [] car = new Car[10];
}
}
Which when I compile says it cannot find the Car symbol. I'm presuming the problem is with the creation of the array as I don't seem to have created the Car properly. Any help would be appreciated <3
当我编译时说它找不到 Car 符号。我假设问题出在数组的创建上，因为我似乎没有正确创建 Car。任何帮助将不胜感激 <3

This is the proper way to create it.
这是创建它的正确方法。
public class Queue {
private Car [] car;
public Queue () {
car = new Car [10];
}
}
Provided that you have defined the car class.
前提是您已经定义了汽车类。

Create a Car Class and put it in classpath and it will work smoothly .
创建一个 Car Class 并将其放在 classpath 中，它将顺利运行。
EDIT[2nd time]: editing my code as per commments below. This shld work
编辑[第二次]：根据下面的评论编辑我的代码。这应该有效
public class Queue {
private Car [] mycar;
public Queue (Car [] car) {
mycar = car;
}
}
EDIT:
编辑：
class Car {
}
