do I need to surround fileInputStream.close with a try/catch/finally block? How is it done?

Question

I have the following Java Class that does one thing, fires out values from config.properties.

When it comes time to close the fileInputStream

Answer 1

The standard approach is:

FileInputStream fileInputStream = null;
try {
    fileInputStream = new FileInputStream(...);
    // do something with the inputstream
} catch (IOException e) {
    // handle an exception
} finally { //  finally blocks are guaranteed to be executed
    // close() can throw an IOException too, so we got to wrap that too
    try {
        if (fileInputStream != null) {
            fileInputStream.close();
        }        
    } catch (IOException e) {
        // handle an exception, or often we just ignore it
    }
}
