Arrays

These work the same as an array in most programming languages. They are of fixed size and a single type.

Defaults

• Reference types -> null
• boolean -> false
• double or float -> 0.0
• int -> 0

Using arrays

• .length is the length of the array
• Traverse them using a loop

Other notes

For-each loops (enhanced for loops) can be used to iterate through an array.
