问题 Fortify security run Noncompliant Code public static A read(String path) throws IOException, ClassNotFoundException { try (ObjectInputStream os = new ObjectInputStream(new GZIPInputStream(new FileInputStream(path)))) { return (A) os.readObject(); } } It is saying "Unreleased Resource: Streams" , but it is inside try-with-resource then what can be the issue? please help me. 回答1: Likely the issue your tool is worried about is if GZIPInputStream or ObjectInputStream throws an exception during

问题 I have the following code in my Android app, and not sure whether it is my Googling skills, but am not able to find a good tutorial on how to monitor progress of InputStream. private void restoreFromUri(Uri uri) { try { InputStream is = getContentResolver().openInputStream(uri); ObjectInputStream ois = new ObjectInputStream(is); ArrayList<String> myList = (ArrayList) ois.readObject(); ois.close(); is.close(); } catch (Exception e) { Snackbar.make(snackView, e.getMessage(), Snackbar.LENGTH

问题 I am attempting to use encryption to communicate over sockets using java. I've successfully communicated with sockets without encryption, but when I try with encryption the program freezes. Here is the parent Connection class that works just fine: public class Connection implements Runnable { protected Socket socket; protected ObjectInputStream objectInputStream; protected ObjectOutputStream objectOutputStream; protected Thread listeningThread; protected Thread dispatchThread; protected

问题 I'm using SocketChannel to send message between a server and a client. Once a client connects with a server, the server opens the InputStreams and OutputStream in a try-with-resources try, to receive messages from the client and send messages to the client, like so: try (ObjectOutputStream out = new ObjectOutputStream(socket.getOutputStream()); ObjectInputStream in = new ObjectInputStream(socket.getInputStream())) {} I want to access out outside of the try. The try contains a while loop that

问题 I'm trying to read some information from a file with ObjectInputStream method. For some reason, the file does not contain the information after the command executed. No error appears. This is my code : public boolean findUser(String user_id) throws Exception { try (ObjectInputStream objectInputStream = new ObjectInputStream(new FileInputStream(fILENAME))){ //System.out.println("Adsfasdf"); System.out.println(objectInputStream); Set<MarkoliaUser> users = (Set<MarkoliaUser>) objectInputStream

问题 What's the main difference between the two? Still both of them are for writing Strings. public void writeUTF(String str) throws IOException Primitive data write of this String in modified UTF-8 format. vs public void writeBytes(String str) throws IOException Writes a String as a sequence of bytes. When should I use one rather than the other? 回答1: It's in the documentation... from DataOutput.writeBytes(String): Writes a string to the output stream. For every character in the string s, taken in

问题 I'm trying to do local IPC using Sockets and Object streams in Java however I'm seeing poor performance. I am testing the ping time of sending an object via an ObjectOutputStream to receiving a reply via an ObjectInputStream over a Socket. Here's the Requestor: public SocketTest(){ int iterations = 100; try { Socket socket = new Socket("localhost", 1212); ObjectInputStream objectInputStream = new ObjectInputStream(socket.getInputStream()); ObjectOutputStream objectOutputStream = new
