Answer:
The correct answer to the following question is an option c) while (inputFile.hasnextInt()).
Explanation:
hasnextint() is the function of the scanner class which is "java.util.Scanner".
This method returns the boolean value so the data type of this method is boolean.
Integer values of radix are assumed only when a next token is in the Scanner input and it returns output True.
The other options are false because the input file can be null and the end of file is not equal to the input file and the next line is equal to the space and also the other options are not the object of the scanner class.
Answer:
signal repeaters.
Explanation:
The best device to use in this scenario would be signal repeaters. These basically grab an already existing signal and repeats it in a specific direction therefore amplifying the range. These devices are usually used when a large network system is not reaching certain devices that are located too far away. These devices are then placed in midpoints between the network and the device and aimed towards the direction of the device. It then picks up the existing signal and retransmits it to the devices' location so that the device can pick up the network signal and access it.
Answer:
Databases are not that simple. Now we not only have a Data warehouse, but we also have the Data Lake as well. We also have NoSQL and SQL form of support with these modern databases. The JSON format is rocking. You can hence through JSON store the text, image, audio, video, etc in one go. And like the first five can be a text, the next five can be an image then again a text than video, and so on. And it is super easy to access them as well. Also, you can edit them quite easily as well. It's not that hard like the Lisp used to be in the past. And supermarket has a mix blend of the database. And modern databases like Data Lake can be very useful, undoubtedly.
You can store security type of requirements, like CCTV footage, each shop details like shop ID, Product list, shop type, electricity bill, hours of opening, floor, facilities, no. of employees, etc., and like this, we can have the details for the entire supermarket, and each shop there definitely.
