Scala supports both one dimensional as well as multi-dimension arrays. A single dimension has one row over n columns and for two-dimension it is actually a matrix of (n*m). Since Array as also like an object so whenever an object is created using the “new” new memory space is allocated in the heap and a reference is returned. Syntax for Array:

The Scala array implementation makes systematic use of implicit conversions. In Scala, an array does not pretend to be a sequence. It can’t really be that because the data type representation …

Scala provides a data structure, the array, which stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more …

Array is a special kind of collection in Scala. On the one hand, Scala arrays correspond one-to-one to Java arrays. That is, a Scala array Array[Int] is represented as a Java int[], an Array[Double] is represented as a Java double[] and a Array[String] is represented as a Java String[]. But at the same time, Scala arrays offer much more than their Java analogues.

Since you created two different objects, and gave no equals method to A they are not equal, since they aren't the same instance. You can provide A with a better equals …

Mar 11, 2019 · Array is a special kind of collection in scala. it is a fixed size data structure that stores elements of the same data type. The index of the first element of an array is zero and the last element is the total number of elements minus one. It is a collection of mutable values. It corresponds to arrays (in terms of syntax) in java but at the same time it’s different (in terms of functionalities) from java.
