Chords Pad GUI - 我希望能够存储三和弦，当我点击一个打击垫时，它会演奏和弦

Question

import com.cycling74.max.*;
import javax.swing. *;
import java.awt.*;
import java.awt.event.*;
import javax.swing.event.*;

这是为了以后的代码创建gui

public class coursework3d extends MaxObject
{
    private program1 win;

    private static final String[] INLET_ASSIST = new String[]{
        "inlet 1 help"
    };
    private static final String[] OUTLET_ASSIST = new String[]{
        "outlet 1 help"
    };

    public coursework3d(Atom[] args)
    {
        declareInlets(new int[]{DataTypes.ALL,DataTypes.ALL});
        declareOutlets(new int[]{DataTypes.ALL,DataTypes.ALL,DataTypes.ALL,DataTypes.ALL});

        setInletAssist(INLET_ASSIST);
        setOutletAssist(OUTLET_ASSIST);

        win = new program1(this);
        win.setVisible (true);


    }

    public void bang()
    {
        int Cmajor[] = {0, 2,  4};
        int CSmajor[] = {1, 5, 8};
        int Dmajor[] = {2, 6, 9};
        int EFmajor[] = {3, 7, 10};
        int Emajor[] = {4, 8, 11};
        int Fmajor[] = {5, 9, 12};
        int FSmajor[] = {6, 8, 13};
        int Gmajor[] = {7, 11, 14};
        int AFmajor[] = {8, 12, 15};
        int Amajor[] = {9, 13, 16};
        int BFmajor[] = {10, 14, 17};
        int Bmajor[] = {11,  15, 18};
    }

    public void inlet(int i)
    {
    }


}

gui框架包含所有面板和jbuttons

        Action Listener for each chord

返回动作监听器，使其发送回最大对象，通过爆炸发挥每个和弦
