我的任務是編寫一個測試程序，提示用戶輸入5個字符串，並使用MyStack和ArrayList以相反的順序顯示它們。我需要幫助瞭解如何接受用戶輸入並將其放入堆棧並反向打印。堆棧和數組列表
My Main:
package arraylist;
import java.util.Scanner;
/**
*
* @author dghelardini
*/
public class ArrayList {
/**
* @param args the command line arguments
*/
public static void main(String[] args)
{
Scanner userIn = new Scanner(System.in);
System.out.print("Enter five names: ");
}
}
MyStack Class:
package arraylist;
/**
*
* @author dghelardini
*/
public class MyStack extends ArrayList
{
private ArrayList<Object> theList = new ArrayList<>();
public boolean isEmpty()
{
return theList.isEmpty();
}
public int getSize()
{
return theList.size();
}
public Object peek()
{
return theList.get(getSize()-1);
}
public Object pop()
{
Object o = theList.get(getSize()-1);
theList.remove(getSize()-1);
return o;
}
public void push(Object o)
{
theList.add(o);
}
@Override
public String toString()
{
return "stack:" + theList.toString();
}
}
