我实现了JAVA的界面设计，麻烦高手帮完成下代码。我也知道要添加响应机制，一个一个功能慢慢添加，但是实在是不知道应该怎样实现有关功能。怎样先谢谢了。我的界面代码如下：
import javax.swing.*;
import java.awt.*;
public class Buttons extends JFrame{
    JButton a1=new JButton("1");
    JButton a2=new JButton("2");
    JButton a3=new JButton("3");
    JButton b0=new JButton("+");
    JButton b1=new JButton("%");
    JButton b2=new JButton("sin");
    JButton a4=new JButton("4");
    JButton a5=new JButton("5");
    JButton a6=new JButton("6");
    JButton b3=new JButton("-");
    JButton b4=new JButton("开平方");
    JButton b5=new JButton("cos");
    JButton a7=new JButton("7");
    JButton a8=new JButton("8");
    JButton a9=new JButton("9");
    JButton b6=new JButton("*");
    JButton b7=new JButton("开立方");
    JButton b8=new JButton("tan");
    JButton a0=new JButton("0");
    JButton a=new JButton("-");
    JButton a10=new JButton(".");
    JButton b=new JButton("/");
    JButton b9=new JButton("log");
