问题

The Java code is

        ObjectInputStream ois=new ObjectInputStream(new FileInputStream("src/Stringdata.txt"));    
        String s=(String)ois.readObject();
        System.out.println(s.toString());

        } catch (IOException e) {

            e.printStackTrace();
        } catch (ClassNotFoundException e) {

            e.printStackTrace();
        }

here am getting java.io.StreamCorruptedException: invalid stream header: 4D6F7374 this error please help me

回答1:

An ObjectInputStream deserializes primitive data and objects previously written using an ObjectOutputStream. src/Stringdata.txt is probably not a file of serialized objects previously written using an ObjectOutputStream. You probably want to use InputStreamReader instead

4D6F7374 is "Most".

This is not a file of serialized objects. It is a text file. Read it with BufferedReader.readLine().

回答3:

Your problem is: Server send/receive data using DataOutputStream/DataInputStream and you are trying to read it in the client side using ObjectOutputStream/ObjectInputStream

Just make sure Server/Client sockets are reading/writing using the same input/output stream types.
