You can build arrays for the following primitives:

  • byte
  • short
  • int
  • long
  • float
  • double
  • char
  • boolean

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

int array

new long[4]

Initializing and accessing array

new int[] {1,2,3,4} [0]
