What are the limitations of Java language?

Answer 1

Some of the limitations of java is: Javacan't have control to hardware resources like ram, processor directly as it doesn't contains pointers. So you can't create kernel of OS, drivers etc. The java code running time is slower than C, that's why frameworks core is still written in C or other low level language
