Arrays and lists

You can build arrays for the following primitives:

For example, new <type>[<size>] or new <type>[] {<comma-separated values>}.

You can use lists such as {<comma-separated values>}.

Lists can contain both non-primitives and primitives.

Access arrays and lists using [index].

Array or list type Example

Array or list type	Example
int array	`new long[4]`
float array	`new float[4]`
Array initializer	`new int[] {1,2,3,4}`
2-dimensional array (cannot have initializer)	`new int[2][2]`
Initializing and accessing array	`new int[] {1,2,3,4} [0]`
Accessing array property	`contacts[0]`
Empty list	`{}`
Integer list	`{1,2,3,4}`
String list	`{'List', 'of', 'Strings'}`
Accessing list element	`{'List', 'of', 'Strings'}[1]`
List with property references	`{user.name.given, user.name.family}`
