使用變量的Java機器人類

Question

我有一個非常簡單的問題，或者至少我認爲它很簡單。目前我正在嘗試使用帶變量的機器人類。我的意思是以下（變量「通行證」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();} 

當我運行程序時，我得到這個錯誤（記住，我只得到這個錯誤時代碼的一部分用 「PASS1，PASS2 ...等。」 是在它）：

Answer 1

Robot#keyPress期望一個int，其表示如在java.awt.KeyEvent

具體描述的虛擬鍵碼，鍵0表示KeyEvent.VK_UNDEFINED這是一個「無效的鍵碼」

不要忘了，直到你調用keyRelease，按鍵將繼續壓制，產生重複鍵按下事件......
