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.
C++: 2.5: 1 Fortran: 2: 0.8 Java: 2.5: 1.5 Perl: 6: 6 Smalltalk: 6: 6.25 Python: 6: 6.5 The literature on programming languages contains an abundance of informal ...
This comparison of programming languages compares how object-oriented programming languages such as C++, Java, Smalltalk, Object Pascal, Perl, Python, and others manipulate data structures. Object construction and destruction

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 ...
Columns 1 though 5 may contain a number which serves as a label. Columns 73 though 80 are ignored and may be used for comments; in the days of punched cards , these columns often contained a sequence number so that the deck of cards could be sorted into the correct order if someone accidentally dropped the cards.
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.
An interpreted version of C/C++, much in the way BeanShell is an interpreted version of Java. Claire: 1994: Yves Caseau: A high-level functional and object-oriented language with rule processing abilities. Cyclone: 2001: Greg Morrisett : Intended to be a safe dialect of the C language.
