Java Primitive Data Ranges

Java defines the following primitive types:
Type Signed? Bits Bytes Lowest Highest
boolean n/a 1 1 false true
byte signed 8 1 -27
-128 		 27-1
+127 
char unsigned Unicode 16 2 0
'\u0000' 		 216-1
'\uffff' 
short signed 16 2 -215
-32,768 		 215-1
32,767 
int signed 32 4 -231
-2,147,483,648 
Integer.MIN_VALUE		 231-1 
2,147,483,647 
Integer.MAX_VALUE
float signed exponent and mantissa 32 4 ±1.40129846432481707e-45 ±3.40282346638528860e+38
with 6 to 7 significant digits of accuracy.
long signed 64 8 -263
-9,223,372,036,854,775,808
Long.MIN_VALUE		 263-1
9,223,372,036,854,775,807  
Long.MAX_VALUE
double signed exponent and mantissa 64 8 ±4.94065645841246544e-324 ±1.79769313486231570e+308
with 14 to 15 significant digits of accuracy.

Java defines the following object wrappers for primitives:

Mutable Primitives Immutable Objects
boolean Boolean
ordinary signed byte Byte
unsigned byte Byte
short Short
char Character
int Integer
long Long
float Float
double Double
char String

Float and Double classes also define: NaN, NEGATIVE_INFINITY and POSITIVE_INFINITY
