坚持使用2D阵列？

Question

我对数组不太好。在下面的代码中有两种方法从两个2D数组中获取数据。第一种方法COMBINATION正常工作。但第二种方法没有。
我在阵列声明???

中做错了什么

下面的方法从数组中获取KeyEvent＆amp;执行Keypress＆amp; keyRelease根据数组中的KeyEvents 例如： Combination.UNICODE_COPY, KeyEvent.VK_CONTROL, KeyEvent.VK_C
上面的行按CTRL + C.它执行复制功能。

我认为在第二种方法中我传递了3个KeyEvents。这是一个问题???

private static final int[][] COMBINATION = {
            {
                    Combination.UNICODE_CUT, KeyEvent.VK_CONTROL, KeyEvent.VK_X
            }, {
                    Combination.UNICODE_COPY, KeyEvent.VK_CONTROL, KeyEvent.VK_C
            }, {
                    Combination.UNICODE_PASTE, KeyEvent.VK_CONTROL, KeyEvent.VK_V
            }
    };

private static final int[][] COMBINATIONS = {
    {
            Combinations.UNICODE_TASK, KeyEvent.VK_CONTROL, KeyEvent.VK_ALT, KeyEvent.VK_DELETE
    }
};

private void keyboardCombination(Combination action)
    {
        boolean exception = false;

        for (int i = 0; i < COMBINATION.length; i++)
        {
            if (action.unicode == COMBINATION[i][0])
            {
                exception = true;

                this.application.getRobot().keyPress(COMBINATION[i][1]);
                this.application.getRobot().keyPress(COMBINATION[i][2]);
                // this.application.getRobot().keyPress(COMBINATION[i][3]);
                this.application.getRobot().keyRelease(COMBINATION[i][1]);
                this.application.getRobot().keyRelease(COMBINATION[i][2]);
                // this.application.getRobot().keyRelease(COMBINATION[i][3]);
                break;
            }
        }
        if (!exception)
        {
            pressUnicode(this.application.getRobot(), action.unicode);
        }
    }

    private void keyboardCombinations(Combinations action)
    {
        boolean exception = false;

        for (int i = 0; i < COMBINATIONS.length; i++)
        {
            if (action.unicode == COMBINATIONS[i][0])
            {
                exception = true;

                this.application.getRobot().keyPress(COMBINATIONS[i][1]);
                this.application.getRobot().keyPress(COMBINATIONS[i][2]);
                this.application.getRobot().keyPress(COMBINATIONS[i][3]);
                this.application.getRobot().keyRelease(COMBINATIONS[i][1]);
                this.application.getRobot().keyRelease(COMBINATIONS[i][2]);
                this.application.getRobot().keyRelease(COMBINATIONS[i][3]);
                break;
            }
        }
        if (!exception)
        {
            pressUnicode(this.application.getRobot(), action.unicode);
        }
    }

组合

public class Combinations extends ControllerDroidAction
{
    public static final int UNICODE_TASK = 40;

    public int unicode;

    public Combinations(int unicode)
    {
        this.unicode = unicode;
    }

    public static Combinations parse(DataInputStream dis) throws IOException
    {
        int unicode = dis.readInt();

        return new Combinations(unicode);
    }

    public void toDataOutputStream(DataOutputStream dos) throws IOException
    {
        dos.writeByte(COMBINATIONS);
        dos.writeInt(this.unicode);
    }
}
