Constructor and Description 

Double(double value)
Constructs a newly allocated Double object that represents the primitive double argument.

Modifier and Type  Method and Description 

byte 
byteValue()
Returns the value of this Double as a byte (by casting to a byte).

static int 
compare(double d1,
double d2) 
int
