的Java而沒有工作，機器人不發送進入

Question

嗨所以我做這個機器人通過jtextfield3

另外回車是不工作的任何幫助，感謝送的時間信息的數字！ 錯誤跑時：

Answer 1

試試這個：

public static void sendkeys(String text) { 
    try { 
     Robot robot = new Robot(); 
     String lol = text.toUpperCase(); 
     for(int i=0;i<lol.length();i++) { 
      robot.keyPress(Character.getNumericValue(lol.charAt(i))); 
     } 
    } catch(java.awt.AWTException exc) { 
     System.out.println("error"); 
    } 

} 

通知robot.keyPress(Character.getNumericValue(lol.charAt(i)))傳遞給Robot.keyPress(int c)

當你通過之前，你的字符轉換成int一個char in一種方法，它會自動轉換爲類型Character，不會打字int

Answer 2

編輯：NonSecwitter的答案是簡單的，可能在所有情況下工作的，所以這個答案很可能是多餘的。

問題是這一行：

robot.keyPress(lol.charAt(i)); 

你需要傳遞int s到Robot.keyPress(int)，不char秒。

做很可能會得到char的int價值的最好的事情：

int c = Character.getNumericValue(lol.charAt(i)); 

然後將其轉換爲KeyEvent常數：

int k = KeyEvent.getExtendedKeyCodeForChar(c); 

這將字符轉換爲相應的鍵碼，我認爲是你想要的。說實話，我不確定是否需要第二步。
