write is that one byte is written
to the output stream. The byte to be written is the eight
low-order bits of the argument b. The 24
high-order bits of b are ignored.
Subclasses of OutputStream must provide an
implementation for this method.

an IOException may be thrown if the

b.length bytes from the specified byte array
to this output stream. The general contract for write(b)
is that it should have exactly the same effect as the call
write(b, 0, b.length).write 在类中 java.io.OutputStreamb - the data.java.io.IOException - if an I/O error occurs.OutputStream.write(byte[], int, int)public void write(byte[] b,

len bytes from the specified byte array
starting at offset off to this output stream.
The general contract for write(b, off, len) is that
some of the bytes in the array b are written to the
output stream in order; element b[off] is the first
byte written and b[off+len-1] is the last byte written
by this operation.write 在类中 java.io.OutputStreamb - the data.off - the start offset in the data.len - the number of bytes to write.java.io.IOException - if an I/O error occurs.public void writeInt(int v)
