13.1 Primitive Data Types

Java supports a complete set of primitive data types, listed in Table 13.1. In Java, the size of each type is defined by the language, and is not implementation dependent, as it is in C.

Table 13.1: Java Primitive Data Types
				Min Value
Type	Contains	Default	Size	Max Value
boolean	`true` or `false`	`false`	1 bit	N.A.
				N.A.
char	Unicode character	`\u0000`	16 bits	`\u0000`
				`\uFFFF`
byte	signed integer	`0`	8 bits	-128
				127
short	signed integer	`0`	16 bits	-32768
				32767
int	signed integer	`0`	32 bits	-2147483648
				2147483647
long	signed integer	`0`	64 bits	-9223372036854775808
				9223372036854775807
float	IEEE 754	`0.0`	32 bits	+/-3.40282347E+38
	floating-point			+/-1.40239846E-45
double	IEEE 754	`0.0`	64 bits	+/-1.79769313486231570E+308
	floating-point			+/-4.94065645841246544E-324
