使用變量的Java機器人類

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。）使用變量的Java機器人類

  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）：

如果PASS1-PASS4是炭灰，不應該'他們是pass1 ='0'等？ – Solace

'0'是一個有效的值嗎？因爲那就是你傳給每個keyPress（傳遞＃）的東西' – aliteralmind

@solace整數0可以轉換爲char。這仍然不一定使它們成爲機器人方法的有效參數值。 –
