Use try...finally syntax.

EXAMPLE:

final BufferedReader r = new BufferedReader(new InputStreamReader(address.openStream()));
try{
    String inLine;
    while ((inLine = r.readLine()) != null) {
        System.out.println(inLine);
    }
}finally{
    r.close();
}

Or even better:

try(final BufferedReader r = new BufferedReader(new InputStreamReader(address.openStream()))){
    String inLine;
    while ((inLine = r.readLine()) != null) {
        System.out.println(inLine);
    }
}

To avoid having to manually do try...catch, try to use scoped guards such as unique_ptr or scoped_guard. Always try to follow RAII principles in classes you write.
