棧中元素的彈出

棧中的彈出操作是指從棧中刪除元素。在對棧執行此操作時，將刪除棧頂的元素，即最後插入棧的元素將首先彈出。（後進先出）

示例

import java.util.Stack;

public class PoppingElements {
   public static void main(String args[]) {
      Stack stack = new Stack();
      stack.push(455);
      stack.push(555);
      stack.push(655);
      stack.push(755);
      stack.push(855);
      stack.push(955);
      
      System.out.println("Elements of the stack are :"+stack.pop());
      System.out.println("Contents of the stack after popping the element :"+stack);
   }
}

輸出

Elements of the stack are :955
Contents of the stack after popping the element :[455, 555, 655, 755, 855]
