Guava : LinkedHashMultimap values as list and not String -
i reading guava's linkedhashmultimap , thought might useful me.
i have requirement such have map follows:
key:value b c d p q p r if above input in map, want use linkedhashmultimap create map like:
key : value list<b,c,d> p list<q,r> tried using linkedhashmultimap has following issue:
maplen.entries().stream().foreach(entry -> { system.out.println("maptemp2 key + " + entry.getkey()); system.out.println("maptemp2 value + " + entry.getvalue()); }); above prints string values in map , not list<string>.
can pointout how can done.
(kindly note: aware of normal core java solution of iterating, checking , creating list , inserting map.)
as can see in javadoc, multimap#entries() returns collection<map.entry<k,v>> - basically, iterate on each key/value pair, instead of key/(value set). so, try turning multimap<k, v> standard map<k, list<v>>. can multimap#asmap(), code like:
maplen.asmap().entryset().stream().foreach(entry -> { system.out.println("maptemp2 key + " + entry.getkey()); system.out.println("maptemp2 value + " + entry.getvalue()); }); ps. guess missed parenthesis after ...entries - it's method, not property, should have used:
// vv down here maplen.entries().stream().foreach(entry -> { system.out.println("maptemp2 key + " + entry.getkey()); system.out.println("maptemp2 value + " + entry.getvalue()); });
