java - 如何确定 ArrayList 迭代器接下来将返回的对象类型？

Question

我有一个ArrayList，我正在使用一个迭代器来遍历它。我需要找出下一个对象的类型:

Iterator vehicleIterator = vehicleArrayList.iterator();

while(vehicleIterator.hasNext())
{
     //How do I find the type of object in the arraylist at this point
     // for example, is it a car, bus etc... 
}

谢谢

Answer 1

Object o = vehicleIterator.next();
if (o instanceof Car) // Is a car
if (o instanceof Bus) // ...
