is there a way to add characters to a stack?
提问by Jay
Is there a way to add characters from a string to a stack without having to create your own push and pop methods?
有没有一种方法可以将字符串中的字符添加到堆栈中，而无需创建自己的 push 和 pop 方法？
Examples would be very appreciated!
示例将不胜感激！

Stack<Character> myStack = new Stack<Character>();
char letter = 'a';
myStack.push((Character) letter);
Create a stack that contains Characterobjects, and cast your chars to Characterbefore you insert them.
创建一个包含Character对象的堆栈，并在插入它们之前将chars 转换为Character。
Java Characterclass: http://docs.oracle.com/javase/7/docs/api/java/lang/Character.html
JavaCharacter类：http: //docs.oracle.com/javase/7/docs/api/java/lang/Character.html
Just like ints and Integers, you need to wrap a primitive before you can insert it in to a data structure.
就像ints 和Integers 一样，您需要先包装一个原语，然后才能将其插入到数据结构中。
Edit: Apparently Stackis deprecated since it inherits from Vector. Here's why: Why is Java Vector class considered obsolete or deprecated?
编辑：显然Stack已弃用，因为它继承自Vector. 原因如下：为什么 Java Vector 类被认为已过时或已弃用？
As Mark Peters indicated, you should use LinkedListor ArrayDeque.
正如 Mark Peters 指出的那样，您应该使用LinkedList或ArrayDeque。

I've decided to answer to this question because there are some misunderstanding...
So,
There is String:
我决定回答这个问题，因为有一些误解......所以，有String：
String s = "your string";
Create Stackor List(LinkedList) look to comment to Answer from Michael
创建Stack或List( LinkedList) 看评论迈克尔的回答
Stack<Character> d = new Stack<Character>();
after all loop with charpush logic
毕竟循环char推逻辑
for (char c : s.toCharArray()) {
d.push(c);
}
And that is all!!!
这就是全部！！！
