java - Is catch block able to catch Throwable (both error and exception) -

-

in 1 of interview, asked me, possible write throwable in catch() this

try{ code } catch(throwable t) { }

i said yes. not give compile time error jvm not handle if there occur error(sub class of throwable ), since errors irreversible conditions can not handled jvm. further asked use of writing throwable .

please give me proper reply can use throwable in catch. if yes why.

it possible catch throwable. , yes, catch instances of java.lang.error problem when comes e.g. outofmemoryerror's. in general i'd not catch throwable's. if have to, should @ highest place of call stack, e.g. main method (you may want catch it, log it, , rethrow it).

i agree argumentation, not make sense catch events you're not able handle (e.g. outofmemoryerror). nice post here.

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. ...
