Array is a special kind of collection in Scala. It is a fixed size data structure that stores elements of the same data type. By using
range() method to generate an array containing a sequence of increasing integers in a given range. We can use final argument as jump to create the sequence. if we do not use final argument, then jump would be assumed as 1.
Below are some examples of array with range:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 1 4 7 10 13
In above example, an array of range (1, 15). In this range difference is not given so by default difference of range will be 1 element. Elements in the array are 1, 4, 7, 10 and 13. Here, we are creating an array of range (1, 15, 3). Which means an array with elements between 1 and 15 and range difference is 3. Elements in the array are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14.
For some of the collections, such as List and Array, we can also create a Range and convert it to the desired sequence: The REPL shows the array that can be created directly from a Range is toArray. We can also use a Range to create a sequence of characters as below:
A B C D E F a c e
In above example, an array of range (‘A’ to ‘F’).toArray. In this, range difference is not given so by default difference of range will be 1 character. characters in the array are A, B, C, D, E and F. Here, we are creating an array of range (‘a’ to ‘f’).by(2).toArray. Which means an array with characters between a and f and range difference is 2. Characters in the array are a, c, and e.
