DataOutputStream(OutputStream)
flush()
size()
write(byte[], int, int)
len bytes from the specified byte array
starting at offset off to the underlying output stream.
write(int)
writeBoolean(boolean)
boolean to the underlying output stream as
a 1-byte value.
writeByte(int)
byte to the underlying output stream as
a 1-byte value.
writeBytes(String)
writeChar(int)
char to the underlying output stream as a
2-byte value, high byte first.
writeChars(String)
writeDouble(double)
long using the
doubleToLongBits method in class Double,
and then writes that long value to the underlying
output stream as an 8-byte quantity, high byte first.
writeFloat(float)
int using the
floatToIntBits method in class Float,
and then writes that int value to the underlying
output stream as a 4-byte quantity, high byte first.
writeInt(int)
int to the underlying output stream as four
bytes, high byte first.
writeLong(long)
long to the underlying output stream as eight
bytes, high byte first.
writeShort(int)
short to the underlying output stream as two
bytes, high byte first.
writeUTF(String)
written
protected int written
DataOutputStream
public DataOutputStream(OutputStream out)
write
public synchronized void write(int b) throws IOException
byte to be written.
write
public synchronized void write(byte b[],
int off,
int len) throws IOException
len bytes from the specified byte array
starting at offset off to the underlying output stream.
flush
public void flush() throws IOException
The flush method of DataOuputStream
calls the flush method of its underlying output stream.
writeBoolean
public final void writeBoolean(boolean v) throws IOException
boolean to the underlying output stream as
a 1-byte value. The value true is written out as the
value (byte)1; the value false is
written out as the value (byte)0.
boolean value to be written.
writeByte
public final void writeByte(int v) throws IOException
byte to the underlying output stream as
a 1-byte value.
byte value to be written.
writeShort
public final void writeShort(int v) throws IOException
short to the underlying output stream as two
bytes, high byte first.
short to be written.
writeChar
public final void writeChar(int v) throws IOException
char to the underlying output stream as a
2-byte value, high byte first.
char value to be written.
writeInt
public final void writeInt(int v) throws IOException
int to the underlying output stream as four
bytes, high byte first.
int to be written.
writeLong
public final void writeLong(long v) throws IOException
long to the underlying output stream as eight
bytes, high byte first.
long to be written.
writeFloat
public final void writeFloat(float v) throws IOException
int using the
floatToIntBits method in class Float,
and then writes that int value to the underlying
output stream as a 4-byte quantity, high byte first.
float value to be written.
writeDouble
public final void writeDouble(double v) throws IOException
long using the
doubleToLongBits method in class Double,
and then writes that long value to the underlying
output stream as an 8-byte quantity, high byte first.
double value to be written.
writeBytes
public final void writeBytes(String s) throws IOException
writeChars
public final void writeChars(String s) throws IOException
writeChar method.
String value to be written.
writeUTF
public final void writeUTF(String str) throws IOException
First, two bytes are written to the output stream as if by the
writeShort method giving the number of bytes to
follow. This value is the number of bytes actually written out,
not the length of the string. Following the length, each character
of the string is output, in sequence, using the UTF-8 encoding
for the character.
size
public final int size()
written field.
