Syntax:

public void write(char[] charArray, int startingIndex, int lengthOfCharArray)



Parameters: This method accepts three mandatory parameters:

  • charArray which is the character array to be written in the Stream.
  • startingIndex which is the starting index from which the portion of character is to taken.
  • lengthOfCharArray which is the length of characters to be written on the stream.

            // Write the portion of the charArray
            // to this writer using write() method
            // This will put the charArray in the stream
            // till it is printed on the console
            writer.write(charArray,
                         startingIndex,
                         lengthOfCharArray);
  
            writer.flush();
