cheap private java hosting Ruby does not have an inject method, but it's easy to write one. In this case we'll add it to the Array class, while on page 100 we'll see how to make it more generally available. class Array   def inject(n)      each { |value| n = yield(n, value) }      n   end   def sum     inject(0) { |n, value| n + value }   end   def product     inject(1) { |n, value| n * value }   end end [ 1, 2, 3, 4, 5 ].sum » 15 [ 1, 2, 3, 4, 5 ].product » 120 Although blocks are often the target of an iterator, they also have other uses.

cheap private java hosting Let's look at a few. Blocks for Transactions Blocks can be used to define a chunk of code that must be run under some kind of transactional control. For example, you'll often open a file, do something with its contents, and then want to ensure that the file is closed when you finish. Although you can do this using conventional code, there's an argument for making the file responsible for closing itself. We can do this with blocks.
