How are bit operations in Java different from C?

Question

Java

Good afternoon, I apologize for a possibly stupid question, but
what is the difference between bitwise operations in Java and C?
As I understand it, you can also write an OS for a PC in Java, but why was Java chosen for Android, and not C?
And in general, is there some dependence that if a language can work with memory, then it is more successful for writing Servers?

You can also write an OS in Java , and it works quite well, but apparently, it has long been abandoned. Android is primarily Linux, and the JVM is spinning there already in user-space; especially since applications are more pleasant to write in some higher-level language than C/C++ . x & 0xff
