Arrays

Arrays allow us to store multiple values in a single variable.
They are distinguished from other variables using brackets: []

    int[] numbers;

Array values consist of the keyword "new", followed by the type, followed by brackets with a number inside.

    numbers = new int[5];

The number in the brackets determine how many indexes this array has.
To access an index, you use brackets to determine which index you want to access.

    numbers[0] = 10;

Arrays are indexed starting at 0.
This means you can access indexes 0 to 4 from numbers, for a total of 5 values.

    numbers[0] = 10;
    numbers[1] = 10;
    numbers[2] = 10;
    numbers[3] = 10;
    numbers[4] = 10;

Arrays have a special property: length
It determines how many indexes there are.

    System.out.println(numbers.length); // prints 5
