Deserialisation issue - java.io.StreamCorruptedException: invalid type code: 00
java,serialization,deserialization,ioexception,corruption
receiveMSG = (Message) deserialize(receivedPacket.getData()); You need to change this to receiveMSG = (Message) deserialize(receivedPacket.getData(), receivedPacket.getOffset(), receivedPacket.getLength); and adjust your 'deserialise()' method accordingly, to accept 'offset' and 'length' parameters, and to use them when constructing the ByteArrayInputStream. EDIT The code you posted doesn't compile: the expression that constructs the outgoing...
Returning a scanner, specifically a File
java,return,try-catch,ioexception
This line: Scanner scanner = new Scanner(new File("Test.txt")); is inside the curly braces of the try block. Therefore, it is visible only within those curly braces. To make sure it's visible outside, declare the variable before the try: Scanner scanner; and then, inside the try block, just assign to it,...
Cannot Load image without absolute path
You put the file in the src folder, therefore its packaged as part of your app. Its not outside your app binary. therefore you must use ClassLoader#getResourceAsStream. Example: BufferedImage img = ImageIO.read(YourClass.class.getClassLoader().getResourceAsStream("mock logo 128x128.png")); ...

Why path is not found in python?
python,python-2.7,numpy,matplotlib,ioexception
The ~ (tilde) is a shell expansion, not a special "filesystem expansion". So ~ expands to the current user directly only when found in a shell command: $echo ~ /home/username But not if used in the filename passed to python's file objects. The python code: open('some/file/name') is equivalent to opening...

Why is InputStream.close() declared to throw IOException while reading the message?
java,inputstream,java-io,ioexception,close
Since close() can throw an IOExection and it is a checked exception, you have the enclose the .close() method inside a try catch block. So that leaves you with another try-catch block inside of a finally block. So your code might look something like this - finally{ try{ if (inputstream...
Why does Scanner use Scanner#ioException() instead of throwing the exception?
java,java.util.scanner,ioexception
The explanation is given by the class documentation for java.util.Scanner. A scanner can read text from any object which implements the Readable interface. If an invocation of the underlying readable's Readable.read(java.nio.CharBuffer) method throws an IOException then the scanner assumes that the end of the input has been reached. The most...
Java input: Scanner or IOException
java,input,java.util.scanner,ioexception
Did you notice, in your example, that when initialising the Scanner you pass it System.in? System.in returns instance of an InputStream (since JDK1.0) The "standard" input stream. This stream is already open and ready to supply input data. Typically this stream corresponds to keyboard input or another input source specified...

Handling IOExceptions in Android
java,android,exception-handling,ioexception
First, read your logcat - you should see your exception there with full stacktrace. Second, there is nothing wrong with catching IOException, but you must do something with it once cached - like inform user of problem in functionality - like no more space, etc. And this is how Android...

Android: Is there any use case where internal file storage can cause an IOException?
You wrote: The only use case could probably be when you run out of space. Other cases: The parent directory does not exist. For example, you're trying to access /data/data/packagename/some_custom_dir_not_yet_created/my_file. You'd need to first call file.getParentFile().mkdirs(). The file you're trying to read does not exist. FileNotFoundException extends IOException. You app...

Throw IOException instead of Exception
You need to save the original exception as the cause, so you're not losing the original message or stacktrace. Calling e.getCause() in your code example is skipping over the exception that you caught and getting its cause, which is suspicious-looking. Also it would be better to specify the particular exceptions...

It isn't necessarily related to the number of write attempts, so changing your interval won't...
