C or C ++ and Java data type table

Java correspondence relationship between data types and C ++ (most available, a small part needs to be adjusted according to actual conditions)

C++	Java
char *	String
word	short
byte	byte
byte[]	byte[]
dword	int
long	NativeLong
Void *	Pointer
lpvoid	Pointer
lpDword	IntByReference
HWND	HWND
char[]	byte[]
byte *	Pointer

Java and C data type table

Java	Types of	C type native performance
boolean	int	32-bit integer (customizable)
byte	char	8-bit integer
char	wchar_t	Platform-dependent
short	short	16-bit integer
int	int	32-bit integer
long	long,__int64	64-bit integer
float	float	32-bit floating point
double	double	64-bit floating point
Buffer/Pointer	pointer	Platform-dependent (32 or 64-bit pointer)
	pointer/array	32 or 64 bit pointer (the parameter / return value) abuts memory (structure member)
String	char*	/ 0 the end of the array (nativeencodingorjna.encoding)
WString	wchar_t*	/ 0 the end of the array (unicode)
String[]	char**	Array / 0 end of the array
WString[]	wchar_t**	Array / 0 end of the wide array of characters
Structure	struct*/struct	A pointer to a structure (parameters or return values) (or is explicitly specified structure pointer) structure (structure member) (or is explicitly specified structure)
Union	union	It is equivalent to the structure
Structure[]	struct[]	Array structure, adjacent memory
Callback	(*fp)()	Java or native function pointer function pointers
NativeMapped	varies	It depends on the definition
NativeLong	long	Platform-dependent (32 or 64-bit integer)
PointerType	pointer	And Pointer same
