How to study two technologies in parallel?

Question

Java

Guys, tell me! How to study two technologies C# and Java in parallel (namely, programming for mobile phones), I myself am a junior, and have been working for about 7 months, at work I use the C# + MSSQL + ASP.NET + Angular stack, i.e. I deal with the web, but I feel that I want to develop for a mobile phone, in connection with this, such a question, how to be?) Is it worth it to simultaneously study the technologies that we use at work and Java for Android? Or do not rush about, and study what is used directly at work? In general, express your opinion, maybe your own experience, in general welcome)

Answer 1

Xamarin in hand and you can safely continue to work on .Net.

Answer 2

As many as two technologies, what a horror!
That's when you have one unlearned language in the TOP10, then you will face a really difficult choice: is it worth learning a language with a disgusting architecture just to be able to confidently declare: "I certainly know ***, but it is not suitable for writing stable and scalable solutions".

Answer 3

No, the technologies are different and they have different approaches. Although there are rumors that C# is stealthy with Java.

Answer 4

You can study, another question is whether you need it and whether it will come in handy. Don't know.
Plus, the moment you have to learn is not java in the full sense of the word. But still android sdk.
