my professor said when ever use static method class whole class gets loaded memory , method executed. my question is: if class contains 100 methods , 50 different variables , if called 1 static method class.the complete class(100 methods , 50 variable ) gets loaded in memory inefficient in terms of memory , performance. how java deals kind of issue ? true, class byte-code loaded when call static method (but once , not every time ).. same happens when call non-static method. in later case instance must created. thus, in sense of question, false dichotomy. because java dynamic language , platform (with jit) runtime efficiency can increase between method invocations. thus, best write clear , concise code (that write dumb code ). if clearest way implement solution static methods use them.

i'm not sure best practice of swift , coredata. think not null property should optional basically? for example import foundation import coredata class item: nsmanagedobject { @nsmanaged var itemid: string // not null property @nsmanaged var itemprice: string? // null possible } i wonder should notify other programmers property not-null or not. i know do usually. question sound opinion-based i'm sure how dealing optional helpful others. fyi found similar question coredata - setting property of entity not null - should attribute set optional or mandatory from https://developer.apple.com/library/mac/documentation/cocoa/conceptual/coredata/articles/cdmom.html#//apple_ref/doc/uid/tp40002328-sw6 .. mentioned - can specify attribute optional—that is, not required have value. in general, however, discouraged doing so—especially numeric values (typically can better results using mandatory attribute default value—in model—of 0)

"</span></td></tr>"; foreach($tests $test){ echo "<tr><td>" . $test . "</td></tr>"; } echo "<tr><td>&nbsp;</td></tr>"; } echo '</table>'; this works ok. need add level nested array, like: $departments[$row['department_name']][$row['group_name']][] = $row['lab_test']; would work , how should adjust each loops above cater this? assign array should [] @ end $departments[$row['department_name']][$row['group_name']][] = $row['lab_test']; foreach...

for example: struct point { int x, int y; }; if threads write own point same location in global memory in same time, possible final result point in location has x value of thread , y value of thread b? this question closely related concurrent writes in same global memory location , is global memory write considered atomic in cuda? [this answer copied comment should have been answer.] is possible final result point in location has x value of thread , y value of thread b? yes. avoid such scenario need write point single atomic value (ie, reinterpret point double or int64 , use atomic set).

i writing application collects huge amount of data , store in neo4j. i'm using java code. in order analyze data want use terminal neo4j server connect same database , use neo4j console query on using cypher. this seems lot of hassle. have changed, neo4j-server.properties connect directory java code collecting data. , changed flag allow_store_upgrade=true in neo4j.properties. however, still facing issues because of locks. is there standard way achieve this? you need have neo4j-shell-<version>.jar on classpath , set remote_shell_enabled='true' config option while initializing embedded instance. i've written blog post on time ago: http://blog.armbruster-it.de/2014/01/using-remote-shell-combined-with-neo4j-embedded/

while reading android samples see comments // begin_include (something) // end_include (something) however, current ide — android studio 1.1 — can not recognise them (or maybe wrong). guess, serve kind of code region marks (like //<editor-fold desc="region name"> // code //</editor-fold> in androidstudio/intellijidea), such syntax c++ preprocessor directives. question: should know important these comments (besides obvious commenting function) improve code in way? it's documentation purposes, used identifying snippets include in target documentation. it's not useful when editing code; it's useful avoiding repetition generating documentation actual code. {@sample} , {@include} these tags copy sample text arbitrary file output javadoc html. the @include tag copies text verbatim given file. the @sample tag copies text given file , strips leading , trailing whitespace reduces indent level of text ind...
