Consider the following method, which is intended to return the product of 3 and the nonnegative difference between two int parameters.

public int threeTimesDiff(int num1, int num2) {

return 3 * (num1 - num2);

}
Which precondition is required so that the method works as intended for all values of the parameters that satisfy the precondition?
A. num1 > 0, num2 > 0
B. num1 >= 0, num2 >= 0
C. num1 >= num2
D. num2 >= num1

Answers

Answer 1

Methods are code segments that are executed when called or evoked.

The required precondition for the method to work as intended is (c) num1 >= num2

The return value of the method is given as:

3 * (num1 - num2).

The return value is said to be non-negative.

So, the following condition must be true

[tex]3 \times (num1 - num2) \ge 0[/tex]

Divide both sides of the equation by 3

[tex](num1 - num2) \ge 0[/tex]

Remove the bracket

[tex]num1 - num2 \ge 0[/tex]

Add num2 to both sides of the equation

[tex]num1 \ge num2[/tex]

Hence, the required precondition for the method to work as intended is (c) num1 >= num2

A check digit, also known as a checksum character, is the number located on the far right side of a bar code. The purpose of a check digit is to verify that the information on the barcode has been entered correctly.

A check digit, even comprehended as a checksum character, stands for the number found on the far right side of a bar code. The intention of a check digit exists to confirm that the information on the barcode contains been documented accurately.

What are the differences between the checksum and check digit?

A checksum in public can be any size, although generally, they exist some suitable number of bits for computation, such as 32. The more extensive the checksum, the wider the range of errors it can capture. For instance, the checksum utilized for credit card numbers will notice changed digits that exist after each other, but not reversed digits that exist split by a single digit.

All cryptographic hashes (like MD5, SHA, etc.) can be utilized as checksums, but not all checksums exist cryptographic. CRC-type checksums aren’t cryptographic, but they’re extremely quick to calculate, and so they exist generally utilized for things like hard drive checksums where you don’t require the cryptographic functionality, but you accomplish want to notice an extensive range of probable errors.

I'm confused as to if subclasses can call the supers without any implementation and what the right answer is

Answers

Answer:

E

Explanation:

Since Example1 and Example2 inherit from Example0, all classes have the method doNothing() at their disposal, so you can call it from e0, e1 and e2.

However, the arguments of this method are Example1 and Example2, so you cannot pass Example0 as a first argument, and you cannot pass Example0 or 1 as a second argument. That only leaves answer E.

You can call the inheritance relation an "is a kind of" relation. So Example1 is a kind of Example0, and Example2 is a kind of Example1, but also Example2 is a kind of Example0.

Now you can understand why e2 can be passed as an argument for Example1, because e2 is a kind of Example1.
