Why wouldn't it make sense?

Is it nonsensical to say that one doesn't know why one doesn't know why something does not make sense ?
Is to ask the above question to advance the hypothesis that what does not make sense is always recursive ?
Let me get back to you on this in a few more kalpas.
cheers, Bill

Makes sense. That could be a sig.

The question really isn't "Why should someone know both?", but "Does is make sense for one company to need both skills in one person?"

I do fine knowing none of them (actually I "know" C#, the little I needed to port an old VS6 Add-In to VS2008 and a little of C++/CLI, the minimum to create a DLL accessible both from VB6 and from .NET), it really depends on the field you work into.
If you work on microcontrollers or have a strong integration with hardware you wouldn't probably need them except on occasional basis.

Yep, I've been an embedded programmer for decades (just love the nitty gritty low level stuff) and pretty much all I need to know is C and some C++. I used Java once for a tester years ago just to see what it was about (no unsigned numbers???). And I recently did another tester but in VB.NET. I'd have used C# but my boss only knows VB and he wants to be able to mess with the code (he's a hardware engineer).

Well - you only need to know what your need to use.
Learn other things that you want to learn.
I do .NET because that's how you write M$ compatible stuff.
I never got around to Java, but C, C++, C#, etc. should get me there if the need arises.
On the other hand, they used to have a java programmer here - and he left for what he thought were greener pastures. They didn't bother replacing him.
The real answer is: you need to know what they expect you to know even before they know what they think need.

I think it's worth learning a couple of languages. I've gone for .NET plus web (HTML/JS/jQuery + Frameworks/CSS + LESS/SASS), SQL and Apple Swift. I'll learn Java when the opportunity appears (probably when I get asked to port an iOS app to Android).
No harm in making yourself more marketable these days, and it's nice to work on a variety of projects

IMHO, a developer should ultimately* become 'language independent', within reasonable limits**. Meaning that (s)he should be able to quickly implement a (an elegant) solution in any of those languages, (with help from Internet resources).
* over a period of ten years, say.
** about 4-5 languages, including a 'GUI language', and a web language.

Experience != Skill
Knowing the foundations of OOP, SQL and some FP I can pretty much write any (major) language with relative ease.
Add to that knowledge of basic structures such as arrays, lists, hashtables, graphs, etc. and some knowledge of common algorithms and you're pretty good to go.
Get familiar with some desktop and some web development too.
Took me about five years.
I'm not saying I know everything (no one ever will) or that I'm some superstar programmer, but I'm sure as hell better than a lot of 10+ years experience seniors I've met (when it comes to programming anyway)

My basic degree is art, culture and media! 
My bachelor degree is Common Art and Cultural Sciences and my masters degree is Media and Journalism.
I only started a part time IT study at the Open University three years ago.
Still haven't finished my 'first year', it's not going very fast...
Doing a lot of hobbying and writing did me lots of good though

Genius! Also, shows your passion towards CS topics!

Not bragging, but one does tend to accumulate a volume of languages over the decades. I'm not entirely certain, but the count was somewhere in the vicinity of 1217, counting all variants and experimental versions. I still have some of the reference manuals from my first projects -- pre-internet.
When I started in the industry, one was required to only know six languages (Basic, COBOL, Fortran, RPG, Assembler and ALGOL/Pascal). All the rest are derivatives of at least one of those six. If you don't believe me, please explain why a large number of language reference manuals contain a syntactic reference section written in Backus-Naur (ALGOL) form.
The difficult may take time, the impossible a little longer.

Wow! Just Wow!
Maybe you should put out all your experiences in a series of articles / tips. Will be really helpful for all the youngsters (and oldsters) out here.

Same here--learned dozens of languages over the years, including some arcane languages such as REPO and EDL.
Found that a language is just a language, i.e., a method for taking some Input, doing some Processing to produce some Output. After a while, the language becomes immaterial. One language might be better suited to accomplish a task than another language, but, with few exceptions, the task can usually be completed in any language.
The harder part is getting a clear definition of the task to be completed, i.e., Input-->Processing-->Output. (Remember HIPO?)

If they actually use Java, then yes. Which does indeed not make sense, if you can use .NET

Eh, I know .NET... I like .NET...
But since all of my .NET projects are on hold for various reasons, I was put on a few Java projects... So I re-taught myself Java... And you know what?
I still like .NET.

Java in itself doesn´t make sense, so what do you think the combination of the two will be?

I use C# (and have used VB.net  ), and wouldn't mind knowing Java for Android, but I really can't be bothered.
(Yes, I've heard of Xamarin, but I don't pay for development tools.)
