title: Which capability exists only in java.io.FileWriter?
body: <p>Which capability exists only in <code>java.io.FileWriter</code>?</p>
  
  <p>A. Closing an open stream. </p>
  
  <p>B. Flushing an open stream. </p>
  
  <p>C. Writing to an open stream. </p>
  
  <p>D. Writing a line separator to an open stream.</p>
  
  <p>I know its not D since line separator is only written using BufferedWriter's newLine() method. But I am not sure which is the correct answer. I have posted this question only after not being able to find the answer.</p>
  
  <p>Please advise.</p>
