This is an example of an InputStream in a try/catch/finally statement. Using try/catch/finally statement to create an InputStream implies that you should:

Create an InputStream and initialize it to null.
Open a try statement and initialize the InputStream to a FileInputStream, by opening a connection to an actual file.
Include the catch statement to catch any IOExceptions thrown while trying to open the connection to the file.
Include the finally statement. Code included here will be executed always. So here the InputStream is closed. A try/catch statement can be included here too, to catch any IOExceptions thrown while trying to close the InputStream.

Let’s take a look at the code snippet that follows:

InputStream in = null;
 
try
{
    in = new FileInputStream(new File("test.txt"));
    //do stuff with in
}
catch(IOException ie)
{
    //SOPs
}
finally
{
    try
    {
 
  in.close();
    }
    catch(IOException ioe)
    {
 
  //can't do anything about it
    }
}
