Java 实例 - 栈的实现

Java 教程 · 2019-02-11 13:27:18

以下实例演示了用户如何通过创建用于插入元素的自定义函数 push() 方法和用于弹出元素的 pop() 方法来实现栈:

MyStack.java 文件

public class MyStack { private int maxSize; private long[] stackArray; private int top; public MyStack(int s) { maxSize = s; stackArray = new long[maxSize]; top = -1; } public void push(long j) { stackArray[++top] = j; } public long pop() { return stackArray[top--]; } public long peek() { return stackArray[top]; } public boolean isEmpty() { return (top == -1); } public boolean isFull() { return (top == maxSize - 1); } public static void main(String[] args) { MyStack theStack = new MyStack(10); theStack.push(10); theStack.push(20); theStack.push(30); theStack.push(40); theStack.push(50); while (!theStack.isEmpty()) { long value = theStack.pop(); System.out.print(value); System.out.print(" "); } System.out.println(""); } }

以上代码运行输出结果为:

50 40 30 20 10
