Question

我有一个非常简单的问题，或者至少我认为这很简单。目前我正在尝试使用带变量的机器人类。我的意思是以下（变量“传递”是字符。）

            pass1 = 0;
            pass2 = 0;
            pass3 = 0;
            pass4 = 0;


                try{
                        Robot robot = new Robot(); 
                        robot.delay(2000);

                        robot.mouseMove(1318, 322);
                        robot.keyPress(pass1);
                        robot.keyPress(pass2);
                        robot.keyPress(pass3);
                        robot.keyPress(pass4);
                        } catch (AWTException e) {e.printStackTrace();}

当我运行程序时，我得到了这个错误（请记住，当代码中带有“pass1，pass2 ......等”的部分在其中时，我才会收到此错误。）：

Answer 1

Robot#keyPress需要一个int，代表java.awt.KeyEvent

中描述的虚拟密钥代码

具体来说，密钥0代表KeyEvent.VK_UNDEFINED，这是“无效的密钥代码”

不要忘记，在你拨打keyRelease之前，会继续按下按键，生成重复的按键事件......

使用变量的Java Robot类
