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.
Answer:
C. 2^16
Explanation:
In Computer Networking, there are five (5) classes of IP addresses, these include;
- Class A
- Class B
- Class C
- Class D
- Class E
The various classes of IP address are represented by the value of their first octet. The first octet value of Class B is 128-191 with a subnet mask of 16.
Hence, from the IP address 149.130.x.y where x and y are 8-bit numbers. The x and y equals 16-bit numbers.
Thus, 2^16 devices can connect to the Wellesley network before we run out of IP addresses.
One is of type int
called hours, initialized to 12, another is of type boolean called
isTicking, initialized to true, and the last one is of type Integer
called diff, initialized to 5.
Answer:
Blockchain transactions allow users to control their data through private and public keys, allowing them to own it. Third-party intermediaries are not allowed to misuse and obtain data. If personal data are stored on the blockchain, owners of such data can control when and how a third party can access it.
