Java - what is a a prototype? -

Image
in lecture on java, computer science professor states java interfaces of class prototypes public methods, plus descriptions of behaviors. (source https://www.youtube.com/watch?v=-c4i3gfye3w @8:47) and @ 8:13 in video says go discussion section teaching assistants learn means prototype. what "prototype" mean in java in above context? i think use of word prototype in context unfortunate, languages javascript use called prototypical inheritance totally different being discussed in lecture. think word 'contract' more appropriate. java interface language feature allows author of class declare concrete implementations of class provide implementations of methods declared in interfaces implement. it used allow java classes form several is-a relationships without resorting multiple inheritance (not allowed in java). have car class inherits vehicle class implements product interface, therefor car both vehicle , product.

Efficiently creating pairs of random array items in PHP that meet certain criteria -

i have 3 arrays: $a 5 elements, , $b & c 4 elements. each member of $a has paired randomly 3 times member $b or $c . however, each element $b , $c has paired randomly five elements other 2 arrays. each of these pairings must unique, , element can't paired itself. eg: $a = array('a1', 'a2', 'a3', 'a4', 'a5'); $b = array('b1', 'b2', 'b3', 'b4'); $c = array('c1', 'c2', 'c3', 'c4'); the pairings a1 like: 'a1', 'b3' 'a1', 'b4' 'a1', 'c2' and pairings c3 like 'c3', 'a2' 'c3', 'b3' 'c3', 'a4' so again, i'm trying make random pairings that: an element must matched elements other arrays (and can't match themselves). can in number either one. each matching must unique elements in $a must matched 3 times, elements in $b or $c must matched 5 ti...

the following confusing me lot. have been spending quite bit of time trying understand why collection.find() doesn't work regex passed object. regex match coming on http wrapped in body of post request. try gather query (in string format) , perform query. problem seems unless regex written inside node without quotes, won't work. is, must literal without quotes. for example, following works fine: var query1 = { company: { '$regex': /goog/ } }; collection.find(query1, {}).toarray(function (err, docs) { // got results back. awesome. }); however, if data comes wrapped in object, doesn't return anything. suspect it's because value gets quoted behind scenes (i.e. "/goog/"): // assume var query2 = { company: { '$regex': query.company } }; collection.find(query2, {}).toarray(function (err, docs) { // got nothing back. }); i have tested mongo shell , can confirm following: // returns 5 results db.getco...
