In that matter, you can find the various answer from the various programmer. But first, you need to ask yourself for which purpose you need to learn programming language.
1. To do a job.
2. To fulfil your carrier goal or
3. To build an application.

So if you try to do a job then I strongly suggest learning Java, because If you notice 365 days you can find opening java in a various company like Intlum and more. But one thing keeps in mind that learning only java is not to get the job you need to learn SQL too. When you make learning J2EE then you may pass HTML, JavaScript and CSS.
Next, you must have to learn frameworks, even you learn java, CSS, HTML No one can give you the job because most of the company used frameworks to build the application.
If you are not a developer and try to make it then again I suggest you learn JAVA. It will not be a tough job for you to explore new tools and Java apis if you already know Java.
Hope these few suggestions make you understand the whole concept.
