Direct access from Java to native operating system and hardware functions requires the use of the Java Native Interface, or since Java 21, the Foreign Function and Memory API, which allow for allocating and managing memory outside of the Java Virtual Machine, as well as calling native (i.e. C/C++) functions.

In C and C++ short, long, and long long types are required to be at least 16, 32, and 64 bits wide, respectively, but can be more. The int type is required to be at least as wide as short and at most as wide as long , and is typically the width of the word size on the processor of the machine (i.e. on a 32-bit machine it is often 32 bits wide ...
Results for microbenchmarks between Java and C++ highly depend on which operations are compared. For example, when comparing with Java 5.0: 32- and 64-bit arithmetic operations, [48] [49] file input/output, [50] and exception handling [51] have a similar performance to comparable C++ programs; Operations on arrays [52] have better performance in C.
A high-level comparison of in-kernel and kernel-to-userspace APIs and ABIs The Linux kernel and GNU C Library define the Linux API. After compilation, the binaries offer an ABI. Keeping this ABI stable over a long time is important for ISVs. In computer software, an application binary interface (ABI) is an interface between two binary program ...
