Java Tutorial 5 – Arrays
In non-trivial computing problems you often need to store lists of items. Often these items can be specified sequentially and referred to by their position in the list. Sometimes this ordering is natural as in a list of the first ten people to arrive at a sale. The first person would be item one in the list, the second person to arrive would be item two, and so on. Other times the ordering doesn’t really mean anything such as in the ram configuration problem of the previous chapter where having a 4 MB SIMM in slot A and an 8 MB SIMM in slot B was effectively the same as an 8 MB SIMM in slot A and a 4 MB SIMM in slot B. However it’s still convenient to be able to assign each item a unique number and enumerate all the items in a list by counting out the numbers.
