Java development time is 15-20% quicker than Kotlin compilation time. However, when it comes to the development lifecycle to assemble compilation, Kotlin performs similarly to Java.

There are numerous distinctions between java vs. c++, some more subtle than others—the difference between c++ and java in terms of platform dependencies, memory management, and class usage. C++ is platform-specific and must be compiled on each platform. Java is platform agnostic. Once completed, it could be executed on every platform when converted to bytecode. Memory management in Java is system-controlled, whereas memory management in C++ is manual.

Java is designed to run on the Runtime Environment (JRE), whereas C# is built to operate just on Common Language Realtime (CLR)
