What is Josh's take on things like the JPA patterns that rely on mutable objects quite heavily? |

it somehow skipped the first few mins (I think) but it jumped straight into the intro with Josh |

The Enum way writting Singleton is mentioned as preffered way but not much is told abouit it advantage. What are the advantages of Enum based Singleton vs static final variable? |

Q: Josh, how do you feel about the philosophy of marking class members as final ? If you feel positive about it, do you feel that classes and methods should have been "final" by default and with a keyword to allow overriding would have been better? |

Is there anything in J9 you're looking forward to or already using now? |

[Q] regarding item 11 (clone method): given the many negative points about the method, would you say never to use it? or does anybody have a good example where it is the right way to copy objects? |

Q: In which scenarios you will recommend using streams? |
| 16:36 |
|
janne_ |
regarding "final": C# and the .NET libraries go in this direction. You need to declare methods "virtual" for them to override. You can also "seal" a class (this is equal to final). and the .NET standard libraries from microsoft have many many sealed classes |
| 16:40 |
|
sury |
Item 7: Hi Josh, do you think that finalize() should be available as a language level api. As of now anyone can just override it without knowing the implications, why not just make it private? |
| 16:45 |

does that means that Singelton should be defined at language level, as to me using enum for Singeleton is like using book for cookie coaster |
| 16:46 |

How defensive should we be against clients using Reflection to defeat immutability or any other imposed constraints? |

@Guest64400 the answer is yes Josh mentioned this in the beginning |

@Guest64400 - Josh earlier indicated that he was trying for 2015. |

Omkar_India |
my question may sound weird... but I don't understand the need of class Object. Except native wait () and notify() methods, other methods are useful only when we override them. Any historical reasons for it? |
| 16:50 |
|
piyushc |
Thanks... :) |

Guest64400 |
Thanks pm771, I just started a little late |
| 16:53 |

carljokl |
I did find it wierd that Object isn't abstract and that you can create instances of them. |
| 16:53 |
|
carljokl |
Though pragmatically it makes them easier to use as locks. |
