  - ### write

    public void write(int b) throws java.io.IOException
    Description copied from class: `OutputStream`
    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. Subclasses of OutputStream must provide an implementation for this method.
    Specified by:
      `write` in class `OutputStream`
    Throws:
      `java.io.IOException`

  - ### write

    public void write(byte[] b) throws java.io.IOException
    Description copied from class: `OutputStream`
    Writes 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).
    Overrides:
      `write` in class `OutputStream`
    Throws:
      `java.io.IOException`

  - ### write

    public void write(byte[] b, int offset, int length) throws java.io.IOException
    Description copied from class: `OutputStream`

    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

    invalid reference

        off

    is the first byte written and b[off+len-1] is the last byte written by this operation.

    The write method of OutputStream calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation. 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.

    Overrides:
      `write` in class `OutputStream`
    Throws:
      `java.io.IOException`

  - ### flush

    public void flush() throws java.io.IOException
    Description copied from class: `OutputStream`
    Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination. The flush method of OutputStream does nothing.
    Overrides:
      `flush` in class `OutputStream`
    Throws:
      `java.io.IOException`

  - ### close

    public void close() throws java.io.IOException
    Description copied from class: `OutputStream`
    Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened. The close method of OutputStream does nothing.
    Specified by:
      `close` in interface `AutoCloseable`
    Overrides:
      `close` in class `OutputStream`
    Throws:
      `java.io.IOException`
