write	back to summary
public void write(byte[] buf, int off, int len) throws IOException Overrides java.io.OutputStream.write. Doc from java.io.OutputStream.write. Writes `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. If `b` is `null`, a `NullPointerException` is thrown. If `off` is negative, or `len` is negative, or `off+len` is greater than the length of the array `b`, then an `IndexOutOfBoundsException` is thrown. Parameters buf:byte[] the data. off:int the start offset in the data. len:int the number of bytes to write. Exceptions IOException: if an I/O error occurs. In particular, an `IOException` is thrown if the output stream is closed.

public void write(byte[] buf, int off, int len) throws IOException

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes 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.

If b is null, a NullPointerException is thrown.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

Parameters

buf:byte[]: the data.
off:int: the start offset in the data.
len:int: the number of bytes to write.

Exceptions

IOException:: if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.

write back to summary

write	back to summary
public void write(int b) throws IOException Implements abstract java.io.OutputStream.write. Doc from java.io.OutputStream.write. Writes the specified byte to this output stream. The general contract for `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. Parameters b:int the `byte`. Exceptions IOException: if an I/O error occurs. In particular, an `IOException` may be thrown if the output stream has been closed.

public void write(int b) throws IOException

Implements abstract java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes the specified byte to this output stream. The general contract for 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.

Parameters

b:int: the byte.

Exceptions

IOException:: if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.
