Json Validation with PlayFramework in Scala - can please help me prepare next code: case class person(name:string,email:option[string]) implicit val personformat:format[person] = ( (__ \ "name").format[string] ~ (__ \ "email").formatnullable[string](email) // code doesn't compile here )(person.apply,unlift(person.unapply)) apparently formatnullable doesn't work readconstraints, how can resolve ? email read[string] while require format[string] here. format combination of read , write cases symmetrical. isn't case here because validation reading json, not writing it. cannot write single format . to around this, write read , write separately: implicit val personreads: reads[person] = ( (jspath \ "name").read[string] ~ (jspath \ "email").readnullable[string](email) )(person.apply _) implicit val personwrites: writes[person] = ( (jspath \ "name").write[string] ~ (j

Java - how should a method with return treat exceptions - i'm doing exercises exception handling , nil working. i'd know how method homecoming should implement exception, instance: public class class{ double n1, n2, result; public double sum(double n1, double n2){ this.n1 = n1; this.n2 = n2; result = n1 + n2; homecoming result; } } this b e class , method, then..what if want create exception makes sure no letters input (the scanner in main class). i tried next code: public double sum(double n1, double n2){ try{ this.n1 = n1; this.n2 = n2; result = n1 + n2; }catch(numberformatexception e){ system.out.println("error!"); homecoming 0; } homecoming result; } but whenever execute , input letter, next error occurs: exception in thread "main" java.util.inputmismatchexception @ java.util.scanner.throwfor(scanner.java:909) @ java.util.scanner.next(scanner.java:153

java - Collapse 2D ArrayList - i have object contains dynamically allocated 2d arraylist . it has getter: arraylist<integer> getlist() i'd function collapse 2d arraylist 1d arraylist . java have such thing or stuck doing this: public arraylist<integer> getlist(){ arraylist<integer> result = new arraylist<integer>(); for(int = 0; < list_.size(); i++){ for(int j = 0; j < list_.get(i).size(); j++){ result.add(list_.get(i).get(j)); } } homecoming result; } without java 8, have utilize loops. using addall(..) rid of 1 of them though. public arraylist<integer> getlist(){ arraylist<integer> result = new arraylist<integer>(); for(arraylist<integer> : list_){ result.addall(i); } homecoming result; } also, generic types such arraylist must object types, hence integer, not int. java arraylist multidimensional-array dynamic-arrays

json - trouble extracting recursive data structures in scala with json4s - i have json format consists of map -> map -> ... -> int arbitrary number of maps per key. keys strings , leaf types ints. depth of map construction varies per key in map. example, key "a" type map[string, int] , key "b" type map[string, map[string, int]]. know can parse format map[string, any], i'm trying preserve types create these structures easier merge later in code. i can't seem define nested construction in such way not throw error on json4s extract. i'm not quite sure if problem in construction definition or if i'm not doing json extract correctly. here code sealed trait nestedmap[a] case class elem[a](val e : a) extends nestedmap[a] case class nmap[a](val e : map[string, nestedmap[a]]) extends nestedmap[a] // xxx next line doesn't seem help or wound case class empty extends nestedmap[nothing] implicit val formats = defaultformats val s
