java - Preventing Prepared Statement Leaks using Checkstyles -

-

lets have following code :

preparedstatement ps = null; resultset rs = null; try {   ps = conn.createstatement(myquerystring);   rs = ps.executequery();   // process results... } catch (java.sql.sqlexception e) {   log.error("an error!", e);   throw new exception("i'm sorry. query did not work."); } {   ps.close();   // if forgot leak   rs.close();   // if forgot leak }

and wished catch scenario forget close preparedstatement or resultset using checkstyles. possible, , if so, how go it?

pmd , findbugs both have warnings preparedstatements (and resultsets , connections). i'd suggest using them type of warning, since checkstyle has more code style finding data-flow bugs such this.

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
