Singleton objects are a cleaner solution than static.It is both object-oriented and functional.It is highly maintainable and productive.Learn Scala Arrays and Multidimensional Arrays in ScalaĪmong various other benefits of the language, here are a few: Since we don’t need the second element yet, Scala doesn’t evaluate it. This lazy computation enhances program performance. In results 20 and 21, we do not assign the expression to any variable, so not that this doesn’t change the original vectors.Ī stream is a lazy list as it evaluates elements only when it needs to. This data structure extends the trait IndexedSeq and the abstract class AbstractSeq. We can use it when we want to hold a huge number of elements and want random access to them. Res18: = BitSet(1, 2, 3, 7, 9)Ī vector is a general-purpose data structure that is immutable. Res16: = BitSet(1, 2, 3, 7, 9) scala> nums-=0 //Deleting an element that doesn’t exist The largest number in a bitset determines its memory footprint. These arrays are variable in size and packed into 64-bit words. This is exception propagation.Ī bitset is a set of non-negative integers depicted as arrays. Whenever it does find a handler, it makes it catch the exception. Failing there, it looks for yet another in the next caller in the chain. When it fails to find one, it searches for one in the caller method. ![]() When a function experiences an exception, it looks for a handler to deal with it. What do you have to say about exception propagation in Scala? Since these let us store data in more than one dimension, we can store data like in a matrix. OfDim() is a method in Scala that lets us create multidimensional arrays.
