I have spent several hours learning the basics of goal is to be able to write a program that will access a certain website & check for certain far, I have only been learning to write simple graphics programs and games...nothing I have found so far in JAVA talks about how to write a program that will access a specific website.

I am new to programming in any language...I need to write a program that accesses a web site (like a hotel website), logs in, and checks for availability during a certain day...and if it finds that date not available, I want the program to keep checking the website several times a day and if/when it finally finds that date to be available I want the program to send me an email to alert me.

Is it possible to write a program in JAVA that will do this?

I just don't want to waste alot of time learning something that can't eventually do what I want...Does anyone know how I can learn the type of JAVA programming I am trying to accomplish without first learning all the simple programs (like graphics programs I am not going to be using)...I am desperate, would be very grateful for any responses....please point me in the right direction! THANK YOU!

PS my computer skills are above average, I do understand the JAVA tutorials I have read, and I have written a few simple programs...I want to learn and I will put in the hours, but I am having trouble finding web-based tutorials that go beyond the simplest buying a book the only answer? I would like to continue learning online...Thanks again!

You can do that in Java (as you can in any number of other programming languages).

It sounds like the interaction is complex, but probably not really difficult. I'd use a library like jWebUnit for this; it can automate interactions with web sites and supports cookies, authentication etc.

For sure in Java you can do it. You can do even more. Java can help you with a lot of support like NetBeans or Eclipse. Anyway you should have knowledge of the libraries and/or available tools even if you have knowlege of the language and that, as you understand is the hard part but internet can help you a lot on this search.
Anyway if you are looking for a simple batch language for fast prototyping I can suggest you also the Python language. It has not so extensive IDEs but has a lot of ready to be used libraries. Personally I used it to retrieve data from sites, synchronize the work of several programs and manipolate the file system. It could be worth to take a lot at it too.

have luck
I agree. Here's the link:
