Scala Array Programs

An array is a linear data structure with a fixed number of elements. It is a collection that stores a fixed number Arrays in Scalf elements of the same datatype. In Scala, an array is 0 indexed, i.e. the first element has an index of zero. The last element of the array has an index of the last element minus one.

The syntax of Scala array creation is just the same as in Java but is a lot more powerful in term of features and methods backing it. It can also support sequence functions in Scala. In Scala, for defining array there is liberty on the data type. i.e., you can skip assigning of the datatype of the array. Also, it supports all types of elements.

An array can extend up to as many dimensions as you want but only 1-D, 2-D, and 3-D arrays are commonly used. Here, we will discuss only a one-dimensional array.

Practice these Scala array programs to learn the concept of array, these programs contain the solved code, outputs, and the detailed explanation of the statements, functions used in the Scala array programs.
