Print out all elements of a stack/queue
提问by user2963286
I am trying to go through a stack and a queue and print out the Object's values. In my Object's class I have implemented a toString. My stack and queue classes use a linked list. I tried going through it with a for loop like an array first, obviously doesn't work. I know how to get the top but not all of them.
我试图通过一个堆栈和一个队列并打印出对象的值。在我的 Object 类中，我实现了一个 toString。我的堆栈和队列类使用链表。我尝试先用像数组这样的 for 循环来遍历它，显然不起作用。我知道如何获得顶峰，但不是全部。
for (i = 0; i <= 9; i++) {
System.out.println(storageA[i].toString());
}
storageA is my stack with fixed size of 10.
storageA 是我的堆栈，固定大小为 10。

Assuming you want to iterate over the complete list holding Objects of type E:
假设您要遍历包含 E 类型对象的完整列表：
for (E element : storageA) {
System.out.println(element.toString());
}
If you really only want elements 0-9 (better validate storageA.size > 9, else you get an IndexOutOfBoundsException):
如果你真的只想要元素 0-9（最好验证 storageA.size > 9，否则你会得到一个 IndexOutOfBoundsException）：
for (i = 0; i <= 9; i++) {
System.out.println(storageA.get(i).toString());
}
