Some Items may correspond to more than one correct choice. In case an item is corresponding to more than one answer, you have to tick on all the correct choices for you to earn the credit allotted for the item.

Suppose the following code segment in a certain method that throws IOException was used to write to a file, 2 points DataOutputStream output = new DataOutputStream(new FileOutputStream("datafile.dat")); output.writeUTF("Test Name"); output.close(); Which of the following may be a code segment for reading the string that was written in the datafile.dat (Assume that the code segment is in a method that throws IOException) Choose your answer from the figure below: * // Option 1 DataInputStream input = new DataInputStream( new FileInputStream ("datafile.data")); System.out.printin(input.readUTF( )); // Option 2 DataInputStream input = new DataInputStream( new FileInputStream ("datafile.data")); System.out.printin(input.readText()); Option 1 Option 2 O None of the above
