Getting an array of all items of a collection in Julia – collect() Method

The collect() is an inbuilt function in julia which is used to return an array of all items in the specified collection or iterator.

Syntax:
collect(collection)
or
collect(element_type, collection)

Parameters:

• collection: Specified collection or iterator.
• element_type: Specified type of elements.

Returns: It returns an array of all items in the specified collection or iterator.

Example 1:

# Julia program to illustrate
# the use of collection() method

# Getting an array of all items in
# the specified collection or iterator.
println(collect(1:2:13))
println(collect(1:4))
println(collect(1:10))
println(collect(1:5:10))

Output:

[1, 3, 5, 7, 9, 11, 13]
[1, 2, 3, 4]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
[1, 6]

Example 2:

# Julia program to illustrate
# the use of collection() method

# Getting an Array with the given
# element type of all items in
# a collection or iterable.
println(collect(Int32, 1:2:5))
println(collect(Int64, 1:5))
println(collect(Float32, 1:2:5))
println(collect(Float64, 1:5))

Output:

Int32[1, 3, 5]
[1, 2, 3, 4, 5]
Float32[1.0, 3.0, 5.0]
[1.0, 2.0, 3.0, 4.0, 5.0]
