    • Method Detail

      • write

        public void write​(int c)
                   throws IOException
        Write a single character. The character to be written is contained in the 16 low-order bits of the given integer value; the 16 high-order bits are ignored.

        Subclasses that intend to support efficient single-character output should override this method.

        Overrides:
        write in class Writer
        Parameters:
        c - int specifying a character to be written.
        Throws:
        IOException - If an I/O error occurs
      • write

        public void write​(String str)
                   throws IOException
        Write a string.
        Overrides:
        write in class Writer
        Parameters:
        str - String to be written
        Throws:
        IOException - If an I/O error occurs
      • write

        public void write​(char[] cbuf,
                          int off,
                          int len)
                   throws IOException
        Write a portion of an array of characters.
        Specified by:
        write in class Writer
        Parameters:
        cbuf - Array of characters
        off - Offset from which to start writing characters
        len - Number of characters to write
        Throws:
        IOException - If an I/O error occurs
      • flush

        public void flush()
                   throws IOException
        Flush the stream. If the stream has saved any characters from the various write() methods in a buffer, write them immediately to their intended destination. Then, if that destination is another character or byte stream, flush it. Thus one flush() invocation will flush all the buffers in a chain of Writers and OutputStreams.

        If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive.

        Specified by:
        flush in interface Flushable
        Specified by:
        flush in class Writer
        Throws:
        IOException - If an I/O error occurs
      • close

        public void close()
                   throws IOException
        Close the stream, flushing it first. Once a stream has been closed, further write() or flush() invocations will cause an IOException to be thrown. Closing a previously-closed stream, however, has no effect.
        Specified by:
        close in interface AutoCloseable
        Specified by:
        close in interface Closeable
        Specified by:
        close in class Writer
        Throws:
        IOException - If an I/O error occurs
