栈,又叫堆栈,是和列表类似的一种数据结构,但是却更高效,因为栈内的元素只能通过列表的一端访问,称为栈顶,数据只能在栈顶添加或删除,遵循 先入后出(LIFO,last-in-first-out) 的原则,普遍运用于计算机的方方面面。 对栈的操作主要有两种,一是将一个元素压入栈,push方法,另一个就是将栈顶元素出栈,pop方法。
数组模拟栈,数据就放在该数组privateint top=-1;// top表示栈顶,初始化为-1//构造器publicArrayStack(int maxSize){this.maxSize=maxSize;stack=newint[this.maxSize];}//栈满publicbooleanisFull(){returntop==maxSize-1;}//栈空publicbooleanisEmpty(){returntop==-1;}//入栈-pushpublic...

Stack 类代码非常简单,其有 3 个核心方法:push、pop、peek。 push 代码语言:javascript 复制 publicEpush(Eitem){addElement(item);returnitem;} 可以看到 push 方法直接调用 Vector 的 addElement 方法将元素插入数组尾部。 pop 代码语言:javascript 复制 ...
