Array
Arrays are lists that store many values of the same type
Index
Array values are stored at a particular index and we access elements in the array by referencing this index value. Index values in Arrays start a 0.
array.length
Returns the length of the array
array[index]
Accesses an element in the array to either update or retrieve.
Traversing an Array
Traversing an array is the process to loop through an array and access each of the elements. Caution must be taken to avoid looping beyond the valid index values.
Enhanced For Loop
A loop that is an alternate to a for or while loop that accesses each value in an array starting at the first value and proceeding in order.
Enhanced For Loop Variable
Variable created in the enhanced for loop header that contains a copy of the array variable.
Common Array Algorithms
Algorithms that are often used in computer science to do basic analysis on a list. These often include traversing and selection processing.
