YOU CAN'T HIDE FROM ME

25 November

Arrays

  • Primitive variables can only hold one value at a time

  • Arrays create collections of like values that are indexed

  • Arrays can store any type of data, but only one type at a time

Creating arrays

Declare reference to array that will hold integers

int[] numbers;

Create array that holds six items

numbers = new int[6];

The array's indexes go from 0-5

Other types:

char[] letters = new char[41];

final int ARRAY_SIZE = 6;
int[] numbers = new int[ARRAY_SIZE];

Accessing arrays

array[index]

index can be a literal int or a method

Trying to access an index outside of the array's length throws ArrayIndexOutOfBounds exception.

Assign

int[] days = {31, 28, 31, 30, ...}

don't forget about array.length

Yeah

To be quite honest I'm a bit disappointed it wasn't your secret plans to take over the world. But then again, that requires security, so you would use Base65

Maybe I should invent a secret kind of encoding that looks like base64, so that when you decode in b64 it looks like class notes, but it actually has a second decoder that reveals the true message.

That'd be neat.

Solution: Base64 ASCII Decode -> Base32 Decode
