你好，java实现开发答题小程序首先要明确您的需求，目前市面上的答题小程序均是在微擎框架基础上开发的应用，比如挑战答题王等，但这有个弊端就是针对开发者来说无法更好进行二次开发，无法按用户的需求实现各类答题模式需求。敬请采纳：上效果图
答题小程序主页面
释义：通过上面的效果图我们可以看到java技术实现的答题小程序，答题模式是比较丰富的，包括：签到、赛季、每日答题、好友PK、排位升级、团队多人赛、还有道具背包等
2、然后我们看一下这里的代码形式：
答题小程序开发界面
上述我们可以看到，小程序端是原生开发的，非h5打包，这样就能满足了原生小程序的流程性。
3、然后我们看一下管理后台
给你一个简单的实现吧，注意一定要先运行MyServerjava
//MyCilentjava

import javaawtevent;
public class MyClient extends JFrame implements ActionListener{
JTextField tf;
JTextArea tx;

PrintWriter out;
public MyClient(){
tf=new JTextField(20);
tx=new JTextArea();
txsetLineWrap(true);
txsetWrapStyleWord(true);
JPanel pan=new JPanel();
JScrollPane jsp=new JScrollPane(tx);
add(jsp,"Center");
bt=new JButton("SEND");
btaddActionListener(this);
panadd(tf);
panadd(bt);
add(pan,"South");
thisaddWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
Systemexit(0);
}
});
setTitle("THE CLIENT");
setSize(400,300);
setVisible(true);
try{
Socket socket=new Socket("127001",1680);
out=new PrintWriter(socketgetOutputStream(),true);
InputStreamReader in = new InputStreamReader(socketgetInputStream());
BufferedReader sin=new BufferedReader(in);

while(true){

txappend("#Server Said#: "+s+"\n");
}

}

这是我编过的程序
它用来计算两个日期之间间隔
某日期向前/后几天是什么日期(考虑闰年)
星期几不好算,肯定要找个基准点
