As an aside, if you want to program homebrew for the nintendo switch (or official API if you can afford it), Rust is a language that is significantly safer and easier to use bugless than C or C++ and it can compile to the Switch, there are a few community made libraries that make it fairly simple to use I hear but never tried them.

In short: No.

In long: Java has a sizeable runtime that that alone is larger than almost every nintendo switch game’s runnable code, combined with the fact of having a GC would cause unending hitches on that much slower hardware. There’s a reason assembly, C, and C++ are used on the switch and only just about that. You ‘might’ be able to do very simple java or python things, but you will quickly run in to performance issues.

Well, I will recommend you to use C/C++ instead of Java as you know that Nintendo Switch primarily uses Nintendo’s own developing environment which includes libraries and tools of C and C++. Whereas Java is versatile programming language which is not natively supported for game development on Nintendo Switch.
