Vector.isEmpty介绍

[英]Returns if this vector has no elements, a size of zero.
[中]如果此向量没有元素，则返回大小为零的值。

Stack<String> stack = new Stack<String>();
 stack.push("1");
 stack.push("2");
 stack.push("3");
 stack.insertElementAt("squeeze me in!", 1);
 while (!stack.isEmpty()) {
   System.out.println(stack.pop());
 }
 // prints "3", "2", "squeeze me in!", "1"
