Answer:
c. You cannot change the name, return type, or parameters of a method defined by the interface.
Explanation:
When implementing an interface:
- The return type of the implementing method should be same as the one defined in the interface.
- The parameters of the implementing method should be the same as defined in the interface.
- The name of the method should be the same as that defined in the interface.
So among the given options , option c is the most relevant as it captures all the above conditions.
Answer:
Means no matter how many processors you use, speed up never increase from 10 times.
Explanation:
If a problem of size W has a serial component Ws,then performance using parallelism:
Using Amdahl's Law:
Tp = (W - Ws )/ N + Ws
Here, Ws = .1,
W - Ws = .9
Performance Tp = (.9 / N) + .1
---------------------------------------------------------
Speed Up = 1 / ( (.9 / N) + .1)
If N -> infinity, Speed Up <= 10
Means no matter how many processors you use, speed up never increase from 10 times.
Answer:
Spam
Explanation:
If you receive in bulk the unsolicited messages, then that does mean that your inbox is being spammed. This will not harm you but you will lose the Gb that is allocated to your mailbox. And if you will not check then your mailbox will soon be full, and you might not receive some of the important messages that you should reply to immediately.
Answer:
c.return Integer.compare(value, otherTemp.value)
Explanation:
The compare() method as the name implies compares two integer values. If they are equal it returns 0, if the first number is smaller it returns -1, and if the first number is greater it returns 1.
It is an Integer class method that is why you need to type Integer.compare() to call the function.
For this example, the parameters that will be compared are <em>value</em>, and <em>otherTemp.value. </em>The type of compareTo method is an integer, we need to return the result.
The answer is encryption
steganography would be hiding data, like in an image
digital forensics is the analysis done after an attack
and the last one is a security standard
