Limits and Size of the primary data types

Limits of the primary datatypes:

Data types	Width (in bytes)	Minimum value	Maximum Value
byte	1	-27	27 - 1
short	2	-215	215-1
int	4	-231	231 - 1
long	8	-263	263 - 1
char	2	0x0	0xffff
float	4	1.401298e-45	3.402823e+38
double	8	4.940656e-324	1.797693e+308

So the sizes in bytes are:
byte - 1 B
short, char - 2B
int, float - 4 B
double, long - 8B

Also to get the limits through java we can get it by their wrapper classes. Click here to see how to get limits programatically.
