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...

IO Exception, my program with input data of x,y sometimes works without any error and randomly sometimes doesnt work with the same x,y input data
The problem exactly was the time to live of the opened port. since i had other functions working at the same time program simply needed more connected time so i expanded timeout to (5000) and also reduced the timer of another Time.Schedule method in another method, and so it worked
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...

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...

Why path is not found in python?

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...

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...
why BufferedReader class producing Exception at compile time not at the run time

Since IOException is a checked exception, you must use either try...catch or 'throws`. Usage of try...catch block is like below.

Java input: Scanner or 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...

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...
