這是我到目前爲止有:的Java:堆棧 - > ArrayList的
System.out.println("\fStack - ArrayList Demo\n");
ArrayList<String> al = new ArrayList<String>();
Stack<String> st = new Stack<String>();
// Start with a few elements to the ArrayList
al.add("A");
al.add("B");
al.add("C");
st.addAll(al); // Retrieve ArrayList elements for the stack and add them there
al.clear(); // Clear arraylist for storage later
// Pop out the last element in the stack.
System.out.println("\nPop out the last element: "+al.add(st.pop()));
System.out.println("What's left of the stack: "+st+"\n");
System.out.println("ArrayList, now: "+al);
// Keep popping..
int count = st.search("A");
while (count != -1 && count >= 1) {
System.out.println("Popping next.."+al.add(st.pop()));
count--;
}
// Is the Stack empty?
System.out.println("\nStack Empty? "+st.empty());
System.out.println("ArrayList now: "+al);
使用al.add(st.pop()));
返回 「真」,當我運行程序。有沒有辦法讓它產生被彈出的實際元素(A,B,C)?
String element = st.pop(); System.out.println(「element is」+ element); al.add(element); – 2013-03-26 21:28:41
String elm = st.pop(); al.add(ELM); ? – kufudo 2013-03-26 21:30:10
@RonDahlgren:和kufudo:你可以用反引號標註代碼中的代碼:' – jlordo 2013-03-26 21:32:41
