Examples of java.io.ObjectInputStream.readUTF()

java.io.ObjectInputStream.readUTF()
Reads and returns primitive data of type String read in UTF format from the receiver @return a String saved as primitive data usingObjectOutputStream.writeUTF() @throws IOException If an IO exception happened when reading the primitive data.

            throws IOException {
        // Read in a string for the sessionId
        ObjectInputStream inControl = new ObjectInputStream(in);
        int port = inControl.readInt();

        String sessionId = inControl.readUTF();
        String hostname = inControl.readUTF();
