guys send your questions to ask Josh! |
| 16:22 |
|
Maldivia |
speaking about almost-deprecated stuff, what about the constant Serializable-tax when adding new stuff? for instance with java8 lambdas can be serializable! |

Hi guys |
| 16:28 |
|
Arslan |
here's a question to all |
| 16:28 |
|
Arslan |
how do you feel about annotations in Java? |
| 16:28 |
|
Arslan |
should they be used sparingly or as much as possible? |
| 16:29 |
|
Arslan |
and why? |
| 16:29 |
|

Can we expect Brian Goetz for "Java Concurrency in Practice" in future ? |

To Josh: Do you know Groovy and if yes what do you think about it? It has many features to reduce verbosity of java code |

Why Java bytes are signed in the first place? |
| 16:36 |
|

Madbit left #virtualJUG |

|
Maldivia |
pm771: all primitive number types in java are signed (well, except char) |
| 16:37 |
|
pm771 |
May be wrongly but I do not see byte as a numeric type. |
| 16:38 |
|
Maldivia |
pm771: it has value range of -128 .. 127, how is that nut a numeric type ? |
| 16:38 |
|
pm771 |
I'm talking about purpose not implementation |

pm771: well, byte being signed or not doesn't really matter though if you don't see them as numeric types! |
| 16:41 |
|
Maldivia |
pm771: their binary representation isn't influenced if the 8th bit is used for sign or not |
| 16:41 |
|
Sajol |
Sometimes it can be seen that rather than handling error by wrapping it by exception as soon as it is found, exception bubble up is done by throwing the exact exception? Is not it better to handle the error as soon as it is found? |
| 16:41 |
|
Sajol |
It would be better if josh discusses regarding this two approaches. |
| 16:41 |
|
Sajol |
Thanks |
| 16:42 |
|
pm771 |
Yes it does. Interpretation of the most significant bit. |

Item 72: don't depend on the thread scheduler, contains lots of "don't do" but not a lot of guidance on how to deal with cases where we can't reduce the number of runnable threads, i.e. 3rd part libraries, any suggestions on how to handle those cases in a portable way? |

pm771: if I do "signed byte b = -1;" or "unsigned byte = 255;" -- they will still have the same binary representation (being all 8 bits set), the interpretation of MSB is only significant if I want to print out the numerical value or do comparison |

If you were going to be stuck on a desert island for years and you could only take three Java classes with you? hahaha. |

If Josh decides to make an early revision of his 3rd edition available for us I'm sure nobody would object. |
