java打印筛选

Question

现在我得到的是这个，但目前在字符串实际存在之前需要屏幕截图导致屏幕截图过早拍摄

        if(string_75_.contains("You have defeated ")) {
            takeScreenshot(true);
        }

这是我的整个版画程序

  static boolean takeScreenshot(boolean verbose){
    try{
      File file = getEmptyFile();
      Wait(50);
      ImageIO.write(getImage(), "png", file);
      if (verbose) {
        System.out.println("Screenshot saved as " + file.getName() + ".");  
      }
      return true;
    }
    catch (IOException e) {
      if (verbose)
        System.out.print("Error saving screenshot.");
    }
    return false;
  }
 private static BufferedImage getImage() throws IOException {
      try {
          Robot robot = new Robot();
          Wait(120);
          robot.keyPress(KeyEvent.VK_ALT);
          robot.keyPress(KeyEvent.VK_PRINTSCREEN);
          robot.keyRelease(KeyEvent.VK_PRINTSCREEN);
          robot.keyRelease(KeyEvent.VK_ALT);
          BufferedImage bufferedImage = (BufferedImage)getClipboard();
          return bufferedImage;
    } catch (AWTException e) {
         BufferedImage bufferedImage = new BufferedImage(765,503 + 11, 1);
         return bufferedImage;
    }
 }

现在主要的问题是等待导致我的应用程序停止了整个但是STILL无法提前截取屏幕截图...任何帮助都是感谢

还有办法清除剪贴板吗？没有我的等待（）它似乎返回最后拍摄的图像，因为它发生的一切都很快

谢谢！
