Why am I getting “must be caught or declared to be thrown” on my program?

by

When you work with I/O in Java most of the time you have to handle IOException which can occur any time when you read/write or even close the stream.

You have to put your sensitive block in a try//catch block and handle the exception here.

For example:

try{
    // All your I/O operations
}
catch(IOException ioe){
    //Handle exception here, most of the time you will just log it.
}
