public final class BinaryStdIn extends Object
boolean
),
8 bits at a time (as a byte
or char
),
16 bits at a time (as a short
), 32 bits at a time
(as an int
or float
), or 64 bits at a time (as a
double
or long
).
All primitive types are assumed to be represented using their standard Java representations, in bigendian (most significant byte first) order.
The client should not intermix calls to BinaryStdIn
with calls
to StdIn
or System.in
;
otherwise unexpected behavior will result.
Modifier and Type  Method and Description
