Question

Considering the following class file, answer each of the questions given below.

import java.io.*; import java.io.FileReader;

import java.io.FileWriter;

public class ReadWrite {

public static void main(String[] args) throws IOException {

    File inputFile = new File("inData.txt");

    File outputFile = new File("outData.txt");

    FileReader in = new FileReader(inputFile);

    FileWriter out = new FileWriter(outputFile, true);

    int c;

    while ((c = in.read()) != -1)

      out.write(c);

    in.close();

    out.close();

}

     }

(11)     in is a FileWriter object.                                                   (a) True (b) False

(12)     out is a FileReader object.                                                 (a) True (b) False

(13)     inputFile is a File object associated with outData.txt . (a) True (b) False

(14)     outputFile is a File object linked with inData.txt .      (a) True (b) False

(15)     out.close() is outside the block of the while loop.             (a) True (b) False

(16)     in.close() is inside the block of the while loop.                  (a) True (b) False

(17)     The while loop is used to both read from and write to the file.    (a) True (b) False

(18)     (c = in.read()) != -1 is true when data can still be read.   (a) True (b) False

import java.io.*; import java.io.FileReader;

import java.io.FileWriter;

public class ReadWrite {

public static void main(String[] args) throws IOException {

    File inputFile = new File("inData.txt");

    File outputFile = new File("outData.txt");

    FileReader in = new FileReader(inputFile);

    FileWriter out = new FileWriter(outputFile, true);

    int c;

    while ((c = in.read()) != -1)

      out.write(c);

    in.close();

    out.close();

}

     }
