我正在调用一个单独的类,我已经在同一个包中编写了我的MainActivity类保存.但是当我运行应用程序时,它给了我java.lang.NoClassDefFoundError.我无法理解为什么无法识别在同一个包中定义的另一个类.我尝试了很多方法,java.lang.NoClassDefFoundError但没有任何方法可以解决错误.

Im watching a directory using Java 7 nio WatchService by using below method.

Path myDir = Paths.get("/rootDir");

try {
  WatchService watcher = myDir.getFileSystem().newWatchService();
  myDir.register(watcher, StandardWatchEventKinds.ENTRY_CREATE, 
  StandardWatchEventKinds.ENTRY_DELETE, StandardWatchEventKinds.ENTRY_MODIFY);

  WatchKey watckKey = watcher.take();

  List<WatchEvent<?>> events = watckKey.pollEvents();
  for (WatchEvent event : events) {
    if (event.kind() == StandardWatchEventKinds.ENTRY_CREATE) {
      System.out.println("Created: " + event.context().toString());
      JOptionPane.showMessageDialog(null,"Created: " + event.context().toString());
    }
    if (event.kind() == StandardWatchEventKinds.ENTRY_DELETE) {
      System.out.println("Delete: " + event.context().toString());
      JOptionPane.showMessageDialog(null,"Delete: " + event.context().toString());
    }
    if (event.kind() == StandardWatchEventKinds.ENTRY_MODIFY) {
      System.out.println("Modify: " + event.context().toString());
      JOptionPane.showMessageDialog(null,"Modify: " …

我需要使用以下方法将我获得的UTC时间字符串转换为本地时间,

String dateCreate = "2013-07-01T04:37:14.771468Z"

DateFormat dfParse = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss'Z'");
dfParse.setTimeZone(TimeZone.getTimeZone("UTC"));
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
df.setTimeZone(TimeZone.getTimeZone("Asia/Colombo"));
java.util.Date dateTime;
dateTime = dfParse.parse(dateCreate);
String dteCreate = df.format(dateTime);

有人可以帮我解决这个问题.:)
