which data structure should use keep elements ordered given weight? need add elements in collection each element generate specific weight, weight not contained (neither calculated) inside element itself; calculated else outside of element. moreover, weight not need stored (but if needed), insert parameter put element @ right position. my specific use case sort music tracks. have list of tracks , list of rules apply on each tracks. iterate through each track, list of rules generate "score" given current track. add track "collection" given generated score, can pick first track highest score. i can't see data structure use in java. have implement new 1 myself? best guess kind of heap data structure, can't figure out 1 specifically. edit: weight calculated once @ beginning. can't provide "comparator" since compare tracks, , can't calculate score on "compareto method". algorithm like: public track determinenext() { my

as far can tell, way sum list<double> using java 8 streams this: list<double> vals = . . . ; double sum = vals.stream().maptodouble(double::doublevalue).sum(); to me, maptodouble(double::doublevalue) seems kind of crufty - sort of boilerplate "ceremony" lambdas , streams supposed dispense with. best practices tell prefer list instances on arrays, , yet sort of summing, arrays seem cleaner: double[] vals = . . . ; double sum = arrays.stream(vals).sum(); granted, 1 this: list<double> vals = . . . ; double sum = vals.stream().reduce(0.0, (i,j) -> i+j); but reduce(....) longer sum() . i has way streams need retrofitted around java's non-object primitives, still, missing here? there way squeeze autoboxing in make shorter? or current state of art? update - answers digest here digest of answers below. while have summary here, urge reader peruse answers in full. @dasblinkenlight explains kind of unboxing necessary, due decisi

i have dynamic form generator user can determine layout of form , use form collect data. first implementation comes mind simplistic one: i have 2 models, form model , formrecords model. form model stores name , layout of form , formrecords model stores form_id , user_id , key-value pairs layout specifies. one problem implementation formrecords model have many entries, implementation used formdata model stored entire set of data specific form , specific user combination in encoded format, ruby hash, might work. feel there speed issues doing during lookup , data manipulation (i.e. select/join) is there better way implement this?

i'm aware of , have used 2 methods in past basic tree structures: adjacency lists , nested sets. understand several pros , cons these approaches - e.g., adjacency lists quick update slow query, nested sets opposite (slow update, quick query). however, require ability store more complex tree-like structures. best way describe using human family relationships. first thought each element have both "ancestors" tree , "descendants" tree. however, there significant redudancy in approach as, using example below, both cameron , kelly share of bob's ancestor tree (and updates more time consuming, insertion tree have insert multiple trees). second thought include tree references. e.g., alice has own ancestor tree. both (4,5) element coming cameron's ancestor tree, , (2,3) element coming kelly's ancestor tree reference alice's ancestor tree. second approach requires less data storage, experience faster updates (only update single tree vs. multiple tre
