Method x1() must either catch IOException or declare that it, too, throws IOException or a superclass of IOException.

Answer: Option 3.

<u>Explanation:</u>

IOException is a special case which developers use in the code to toss a disappointment in Input and Output activities. It is a checked exemption. The software engineer needs to subclass the IOException and should toss the IOException subclass dependent on the specific circumstance.

It can toss an IOException when the either the stream itself is adulterated or some mistake happened during perusing the information for example Security Exceptions, Permission Denied and so on as well as a lot of Exceptions which are gotten from IOException .

If your computer determines the destination address of a network packet is to a remote network.
Arisa [49]

The data link layer software would replace the MAC address of the next hop or gateway when the destination address of a network packet is to a remote network.

<h3>What is a data link layer?</h3>

The data link layer is the second layer of the OSI model and it can be defined as an interface between the network and physical layer. Also, it comprises two (2) main sublayers and these include the following:

  • Logical link control (LLC) layer.
  • Media access control (MAC) layer.

In Computer networking, the data link layer software would replace the MAC address of the next hop or gateway when the destination address of a network packet is to a remote network.
