Difference between object and class in Scala

A class is a definition, a description. It defines a type in terms of methods and composition of other types. An object is a singleton -- an instance of a class which is guaranteed to be unique. For every object in the code, an anonymous class is created, which inherits from whatever classes you declared object to implement. This class cannot be seen from …

How can I use Scala concurrent programming to do computations …

@Jim - There is overhead associated with setting up the problem and you can''t get the answer until the slower of the two threads finishes (and one will be slower if for no other reason than that CPU may be used to do more operating system tasks).

In multi-stage compilation, should we use a standard serialisation ...

In theory, Scala Pickling would be the direction of improvement in which the compiler presents type information and emits appropriate serialization and deserialization code into JSON or some binary format. However, in my own experience, there were major issues in the detail because it guessed how an object should be constructed, and it often guessed …

Use schema to convert AVRO messages with Spark to DataFrame

OP probably resolved the issue but for future reference I solved this issue quite generally so thought it might be helpful to post here. So generally speaking you should convert the Avro schema to a spark StructType and also convert the object you have in your RDD to Row[Any] and then use:

scala

When you use collect() you are basically telling spark to move all the resulting data back to the master node, which can easily produce a bottleneck. You are no longer using Spark at that point, just a plain array in a single machine. To trigger computation just use something that requires the data at every node, that''s why executors live on top of a distributed file …

scala

Firstly, apply and unapply are not necessarily opposites of each other. Indeed, if you define one on a class/object, you don''t have to define the other. apply. apply is probably the easier to explain. Essentially, when you treat your object like a function, apply is the method that is called, so, Scala turns:

How can I use a combination of Scala, Groovy, and Java code …

Well, this might not be the answer you''re looking for, but AFAIK, the porting of Groovy to Android has been tried twice and never completed. There was a GSoC proposition this summer, but I don''t know if it has been picked up. Which means no groovy code can run on a Dalvik VM just yet, and of course gradle cannot do anything about that.

Scala (programming language)

The design of Scala started in 2001 at the École Polytechnique Fédérale de Lausanne (EPFL) (in Lausanne, Switzerland) by Martin Odersky followed on from work on Funnel, a programming language combining ideas from functional programming and Petri nets. Odersky formerly worked on Generic Java, and javac, Sun''s Java compiler.. After an …

Is there a way to avoid to convert number types in Scala? Should I …

For the record, things like toInt or toFloat are not casts, they''re conversions. In conversions a method is called to execute some code to transform a value that is usually a new value. In contrast, casting in Scala is notated with asInstanceOf casting an existing value is simply asserted to have a different type (either narrower or, sometimes, wider).
