The input type “file” brings up a button for a file select box on the browser together with a text field that takes the file […]

An IN parameter is a parameter whose value is passed into a stored procedure/function module. The value of an IN parameter is a constant; it can’t be changed […]

When reading and writing text files :

it is almost always a good idea to use buffering (default size is 8K)
it is often possible to use references to abstract base classes, instead of references to specific concrete classes
there is always a need to pay attention to exceptions (in particular, IOException and FileNotFoundException)

The close method :

always needs […]
