利用棧將輸入的十進制數及一些基本的棧操作

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Stack;

import javax.swing.JScrollPane;



class test {
  public static void main(String[] args) throws NumberFormatException, 

IOException{
	  Stack stk = new Stack();
	  System.out.print("請輸入一個正整數：");
	  BufferedReader strin=new BufferedReader(new InputStreamReader

(System.in));
	  int temp=Integer.parseInt(strin.readLine());
	  do{
		  //用堆棧 10 % 2 把餘數壓入堆棧後 再彈出
		  stk.push(temp%2);
		  temp=temp/2;
		  
	  }while(temp!=0);
	  while(!stk.empty()){
		  System.out.print(stk.pop()+" ");
	  }

/*一些對棧的基本操作

/*壓棧
int push(SqStack *s,ElemType e)
{
  if(s->top<StackSize-1)
  {
     s->top=s->top+1;
     s->data[s->top]=e;
     return 1;

/*出棧

ElemType pop(SqStack *s)
