1.Stack继承于Vector,通过数组实现 (不要用啦!淘汰啦!) Stack<Integer> st =newStack<Integer>(); System.out.println("stack:"+st); //输出 st.push(a); //压栈 Integera=(Integer)st.pop(); //出栈 peek();返回堆栈顶部的元素,但不删除它。 boolean empty(); int search(Object element):确定...
如果使用了泛型,则Vector内只能添加同样类型的对象(泛型指示的对象);如果没使用泛型,那么我们可以把任意的Object类型对象(Boolean/Character/Byte/Short/Integer/Long/Double/Float)添加进Vector,但是不能把基本数据类型(Boolean/Char/Byte/Short/Int/Long/Double/Float)放入Vector中。 如:int i=10; Integer ig=new I...
length; ++i) sum += ((Integer)o[i]).intValue(); System.out.println("sum: " + sum); // sum: 10 2. LinkedList 链表 代码语言:javascript 复制 LinkedList ll = new LinkedList(); ll.add("F"); ll.add("B"); ll.add("D"); ll.add("E"); ll.add("C"); ll.addLast("Z"); ...
