java - When should one create new Thread Groups -

-

i wondering, advantages of assigning threads thread group instead of containing them in 1 (the main) group?

assuming there 10 or more active threads, , couple of threads been initiated every , again application requires, how 1 approach grouping these?

thanks, adam.

there no advantage @ all. threadgroups there backward compatibility, i've never seen them used.

here's brian goetz (author of java concurrency in practice - bible) said them long time ago:

the threadgroup class intended useful in structuring collectionsof threads groups. however, turns out threadgroup not useful. better off using equivalent methods in thread. threadgroup offer 1 useful feature not (yet) present in thread: uncaughtexception() method. when thread within thread group exits becauseit threw uncaught exception, threadgroup.uncaughtexception() method called. gives opportunity shut down system, write message log file, or restart failed service.

threads have uncauht exception handler, , single reason use thread groups isn't valid anymore.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
