You need a finalize to clean up gracefully any Objects or resources that require it. You should always close a Socket Connection and not just drop it because this can tye up resources on the host computer. You can include things like database connections, files that maybe open etc.
If a class already has a finalize and you subclass, the finalize is there for a reason(Usually) and to ensure it gets cleaned up you need to include on

public viod finalize()
{
    super.finalize();
    //any thing else you may need to do
}
