# 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]
```
