使用变量的 Java 机器人类

Question

我有一个非常简单的问题，或者至少我认为它很简单。目前我正在尝试将机器人类与变量一起使用。我的意思如下(变量“pass”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，我收到此错误(请记住，只有当其中包含“pass1、pass2...等”的代码部分时，我才会收到此错误。):

Answer 1

Robot#keyPress需要一个 int，它表示虚拟键代码，如 java.awt.KeyEvent 中所述。

具体来说，键0代表KeyEvent.VK_UNDEFINED，它是“无效的键代码”

不要忘记，在调用keyRelease之前，按键将继续被按下，生成重复的按键事件...
