Exam 1z0-819 topic 1 question 25 discussion

D is the correct answer. The read(char[] cbuf) method of FileReader reads characters from the file and stores them in the characters[] array.

/** * Reads characters into an array. This method will block until some input * is available, an I/O error occurs, or the end of the stream is reached. * * @param cbuf Destination buffer * * @return The number of characters read, or -1 * if the end of the stream * has been reached * * @exception IOException If an I/O error occurs */ public int read(char cbuf[]) throws IOException { return read(cbuf, 0, cbuf.length); }

D for sure. Tested!

Correct answer is D A & B will show an error because : The method readLine() is undefined for the type FileReader. C will show an error because : Cannot invoke read() on the array type char[]

readers.read() will return integer value So D is correct

reader.readline doesn't exist

The correct answer is D
