in interface DataInput
true
or false
EOFException
- if the value could not be read because no
more data remains to be read
IOException
- if an I/O error occurspublic byte readByte() throws IOException
This method is the counterpart for the

EOFException
- if the value could not be read because no
more data remains to be read
IOException
- if an I/O error occurspublic int readUnsignedByte() throws IOException
This method is the counterpart for the

method when it is used with
unsigned 8-bit values.

in interface DataInput
int
value in the range 0x00 to 0xFF
EOFException
- if the value could not be read because no
more data remains to be read
IOException
- if an I/O error occurspublic short readShort() throws IOException
This method is the counterpart for the
DataOutput.writeShort(int)
method.
readShort
in interface DataInput
short
value
EOFException
- if the value could not be read because no
more data remains to be read
IOException
- if an I/O error occurspublic int readUnsignedShort() throws IOException
This method is the counterpart for the

method when it is used with
unsigned 16-bit values.
readUnsignedShort
in interface DataInput
int
value in the range of 0x0000 to 0xFFFF
EOFException
- if the value could not be read because no
more data remains to be read

in interface DataInput
int
value
EOFException
- if the value could not be read because no
more data remains to be read
IOException
- if an I/O error occurspublic long readLong() throws IOException
This method is the counterpart for the

method.
readFloat
in interface DataInput
float
value
EOFException
- if the value could not be read because no
more data remains to be read
IOException
- if an I/O error occurspublic double readDouble() throws IOException
This method is the counterpart for the
DataOutput.writeDouble(double)
method.
readDouble
in interface DataInput
double
value
EOFException
- if the value could not be read because no
more data remains to be read
IOException
- if an I/O error occurspublic String readLine() throws IOException
This method does not have a counterpart in the
DataOutput
interface. Furthermore, this method is
defined as operating on bytes and not on characters, and thus it should
be selected for use only after careful consideration, as if it were
deprecated.
readLine
in interface DataInput
IOException
- if an I/O error occurs.public String readUTF() throws IOException
This method is the counterpart for the
DataOutput.writeUTF(java.lang.String)
method.
readUTF
in interface DataInput
UTFDataFormatException
- if the bytes that were read were not
a valid UTF-8 encoded string
EOFException
- if the value could not be read because no
more data remains to be read
IOException
- if an I/O error occurs
