Reading and Writing Booleans
The
DataOutputStream
class has a
writeBoolean()
method and the
DataInputStream class has a corresponding
readBoolean()
method:
public final void writeBoolean(boolean b) throws IOException public final boolean readBoolean() throws IOException
Although theoretically a single bit could be used to indicate the
value of a boolean, in practice a whole byte is
used. This makes alignment much simpler and doesn’t waste
enough space to be an issue on modern machines. The
writeBoolean() method writes a zero byte (0x00) to
indicate false, a one byte (0x01) to indicate
true. The readBoolean() method
interprets
as false and any positive number as
true. Negative numbers indicate end of stream and
lead to an EOFException being thrown.
