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。目前我正在尝试使用带变量的机器人类。我的意思是以下（变量“通行证”的字符。）

  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，我得到这个错误（记住，我只得到这个错误时代码的一部分用 “PASS1，PASS2 ...等。” 是在它）：

Answer 1

Robot#keyPress期望一个int，其表示如在java.awt.KeyEvent

具体描述的虚拟键码，键0表示KeyEvent.VK_UNDEFINED这是一个“无效的键码”

不要忘了，直到你调用keyRelease，按键将继续压制，产生重复键按下事件......
