在Java中，如果找不到输入文件，如何停止尾部线程

tail-listener

public static void main(String[] args) {
if (listOfFiles[i].isFile()) 
{
 files = listOfFiles[i].getName();
 File pcounter_log = new File(files);                                
 Tailer logMessages = new Tailer(pcounter_log, new FileListener(files,element.getLogPattern()),
                                        5000, true);
 Thread thread = new Thread(logMessages);  
     thread.start();

}

public class FileListener extends TailerListenerAdapter {

 private final String fileName;

 public FileListener(String fileName, ArrayList<String> pattern) {
    this.fileName = fileName;
 }
  public void handle(String line) {

    System.out.println(fileName+\"<---->\"+line); 
    }
}
