我在官网上扒的例子
为什么会报异常呢
例子入下：
- Java code
// Get a list of java.io.File objects. List myObjs = new ArrayList(); // Create a new Query. Query q = new Query(); // Execute the query. QueryResults qr = null; try { // Parse the SQL you are going to use. q.parse("SELECT name,length FROM java.io.File WHERE name LIKE '%.java'"); qr = q.execute(myObjs); } catch (QueryParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (QueryExecutionException e) { // TODO Auto-generated catch block e.printStackTrace(); } // Cycle over the query results. List res = qr.getResults(); System.out.println(res.size()); for (int i = 0; i < res.size(); i++) { // Do something with the File. } 异常信息：
