This is more a question of pros/cons between PHP and JAVA. Iv been doing research, and iv narrowed it down to those two.
And in consideration, id like to go into mobile app dev...So thats +1 for Java.
Time taken to learn the language is not an issue...Just would like to know which is the most effective between the two languages mentioned above.
And on a slight note. Can Javascript work with Java? And what is the real advantage of that?
All answers are appreciated, thanks in advance.
I'm sorry, but PHP and Java are not the only choices. Ruby on Rails and Python's Django framework are both excellent tools for web development. While I haven't used it, Groovy's Grails framework is also very highly reviewed (largely by ex Java programmers). In certain (admittedly obscure) circumstances it's even advisable to do something off the wall like write a CGI program in C. It all depends on what you're trying to do.
Mobile app dev shouldn't influence your choice here, because no matter what web framework you're working with a mobile app is a whole new ball of wax.
So, here's the deal: asking people to compare PHP and Java really won't get you any meaningful answers -- you don't have the background necessary to understand what we'll say. You really need to figure out what you're trying to do before you choose your tool. It's like saying "I'm thinking about building a house, should I use a screwdriver or a hammer?" Here is what I would advise:
Once you've got that base of experience come back and ask this question again. You'll actually be equipped to understand the answers. Of course, once you've got that experience you won't need to ask the question because you'll already know the answer.
Stop trying to kill two birds with one stone. There are different tools for different tasks. You can write mobile apps with Java but you can't write web apps with it. You'll have to use a server-side programming language such as PHP, Ruby on Rails, Django (Python), etc.
And in consideration, id like to go into mobile app dev...So thats +1 for Java.
How is that +1 for Java? We're talking about server-side languages.. you're not running your server off a phone are you? Sure, you can use Java to build apps in addition to running your website, but that's a different story.
Time taken to learn the language is not an issue...Just would like to know which is the most profitable at the end of all the training.
Neither language will make your site more profitable, but you may be in higher demand with different companies depending on what you know.
And on a slight note. Can Javascript work with Java? And what is the real advantage of that?
Well... yes, but that's almost a nonsensical question. You use Java or PHP to produce the HTML that gets sent to the client, and then your JavaScript manipulates that. It's completely unrelated to what language you use server-side.
@comment: I can't really say which is more worth learning. I suppose Java is more versatile in that it has more applications outside the web. PHP is supported by more web-servers though (AFAIK), so you won't have trouble if you need to work on a different server.
I can't fairly recommend one over the other though. I've only used PHP for web, and Java for non-web. I like PHP because it's easy to pickup, easy to use, and all sorts of stuff is built into the language without any includes or anything. Has a big community, so there's lots of scripts you can download. One might argue that it's also a mess of a language, but as long as you aren't all uppity about that sort of thing, it's not really a problem. Java OTH... I don't know. I'm not a Java keener, that's all I'll say :)
Your question really indicate you need to learn alot about web development and programming in general, so I could answer your question but.. I'd recomend you go read up a little.
I think you need to outline the context of your question. For example, if you are looking to get a job in IT, then the language that is most asked for in job ads is the one you want. If on the other hand, you have an application in mind that you would like to write, then you need to tell people (without giving away the details) what type of application it is so that they can tell you the most suitable languages/APIs to for that area.
But remember this - there is no such thing as a super programming language that is the best for everything. Each language is suitable for a range of tasks in a range of contexts, and is usually awful for everything else. Without the context of where the language will be used, no-one can tell you which is better.
Most of the answers here should be able to direct you towards your answer though I would just like to say if you are going to learn a programming language to make Web Apps learn Java, not because this will be the best tool for the job, each job is different, but knowing a full fledged language you will be able to quickly adapt to other languages.
You don't learn a language, you learn the concepts behind programming, then apply them to different languages.
Some feedback:
Seriously, judging by your post, I would advise you to start learning PHP and Javascript.
You already have a web browser so you can start writing javascript now.
As for PHP just install XAMPP from http://www.apachefriends.org/en/xampp.html and after a double click you'll be ready for web development.
After learning what its all about you'll be able to then check out Java and see if it is more effective in what you are trying to do.
