<span>Polymorphic message
Methods in different classes with a similar function are given the same name.
- Makes classes easier to use because programmers need to remember fewer method names.
- Employed as much as possible.
- Polymorphic message ex. is the toString method.</span>
The answer is Hypothesis. It is something more than just a wild guess but less than a well-established theory, a theory which can be tested through study and experimentation.. They are assumptions generally believed to be true. They are provisionally accepted in order to interpret certain events or phenomena, and to provide guides for further study.
Answer:
Selective Repeat protocols
Explanation:
It is better to make use of the selective repeat protocol here. From what we have here, there is a high error rate on this channel.
If we had implemented Go back N protocol, the whole N packets would be retransmitted. Much bandwidth would be needed here.
But we are told that bandwidth is limited. So if packet get lost when we implement selective protocol, we would only need less bandwidth since we would retransmit only this packet.
Answer:
The equal sign "=" must be used.
Most, if not all, spreadsheet programs support formulas, but you must start them with an equal sign.
Answer:
The main method should simply terminate if the FileNotFoundException occurs.
Explanation:
Considering the full code snippet
snippet:public static void main(String[] args) throws FileNotFoundException
public static void main(String[])
represent the entry point method to a java main method
The addition of
throws FileNotFoundException
widens the scope of the main method to explicitly specifies that an exception named the FileNotFoundException may be thrown.
So, if any part of the code explicitly throws the FileNotFoundException the compiler makes use of this to throw an exception.
By throwing an exception, the main method is not catching any exceptions, instead it handles the FileNotFoundException by throwing it to the source which invoked the main method
This is required by the compiler to terminate the program if the FileNotFoundException occurs.
