public class Stack
int[] data;
int maxSize;
int top;
public Stack(int maxSize)
this.maxSize = maxSize;
data = new int[maxSize];
top = -1;
/**
* 依次加入数据
* @param data 要加入的数据
* @return 添加是否成功
*/
public boolean push(int data)
if(top+1== maxSize)
System.out.println(“栈已满!”);
return false;
this.data[++top] = data;
return true;
/**
* 从栈中取出数据
* @return 取出的数据
*/
public int pop() throws Exception
if(top==-1)
throw new Exception(“栈已空!”);
return this.data[top--];
public static void main(String[] args) throws Exception
Stack stack=new Stack(1000);
stack.push(1);
stack.push(2);
stack.push(3);
stack.push(4);
stack.push(5);
while(stack.top>=0)
System.out.println(stack.pop());
