Interface java.io.DataOutput
- public interface DataOutput
The data output interface is implemented by streams that can
write primitive Java data types to an output stream in a
machine-independent manner.
- Since:
- JDK1.0
- See Also:
- DataInput, DataOutputStream
-
write(byte[])
- Writes
b.length
bytes from the specified byte array
to this output stream.
-
write(byte[], int, int)
- Writes
len
bytes from the specified byte array
starting at offset off
to this output stream.
-
write(int)
- Writes the specified byte to this data output stream.
-
writeBoolean(boolean)
- Writes a
boolean
value to this output stream.
-
writeByte(int)
- Writes an 8-bit value to this output stream.
-
writeBytes(String)
- Writes a string to this output stream.
-
writeChar(int)
- Writes a
char
value to this output stream.
-
writeChars(String)
- Writes a string to this output stream.
-
writeDouble(double)
- Writes a
double
value to this output stream.
-
writeFloat(float)
- Writes a
float
value to this output stream.
-
writeInt(int)
- Writes an
int
value to this output stream.
-
writeLong(long)
- Writes a
long
value to this output stream.
-
writeShort(int)
- Writes a 16-bit value to this output stream.
-
writeUTF(String)
- Writes a Unicode string by encoding it using modified UTF-8 format.
