使用堆棧向後打印單向鏈表的數據

Question

我想使用堆棧向後打印單向鏈表的數據，但是卡住了。 Stack類如下：

public class Stack{ 

    public boolean isEmpty(){};  
    public void push(int n){};  
    public int peek(){}; 
    public int pop(){}; 

} 

public class node{ 
    int data; 
    node next; 

} 

public class list{  
    node first;  
} 

Answer 1

Stack<String> stack = new Stack<String>(); 
    List<String> list = new ArrayList<String>(); 

    list.add("a"); 
    list.add("b"); 
    list.add("c"); 

    for (String s: list){ 
     stack.push(s); 
    } 

    while (!stack.isEmpty()){ 
     System.out.println(stack.pop()); 
    }
