Answer:
words.hasNext()
Explanation:
Given the code snippet below:
- while (inputFile.hasNextLine()) {
- String word = "";
- String line = inputFile.nextLine();
- Scanner words = new Scanner(line);
- while (words.hasNext()) {
- word = words.next();
- }
- System.out.println(word); }
- }
We have a inputFile Scanner object that can read data from a text file and we presume the inputFile has read several rows of data from the text file. So long as there is another line of input data available, the outer while loop will keep running. In each outer loop, one line of data will be read and assign to line variable (Line 3). Next, there is another Scanner object, words, which will take the current line of data as input. To get the last word of that line, we can use hasNext() method. This method will always return true if there is another tokens in its input. So the inner while loop will keep running so long as there is a token in current line of data and assign the current token to word variable. The word will hold the last token of current line of data upon exit from the inner loop. Then we can print the output (Line 8) which is the last word of the current line of data.
Answer:
A game is built from a combination of sub-tasks in order to provide the best experience to the user and make sure that the interface is comprises of only the results of the ongoing sub-tasks to provide a higher degree of data abstraction.
Data abstraction refers to the process of representing the essential information without including the background details. Rolling a dice is preferred to be a sub-task so that the user only gets to know about the result of the roll and does not have to wait for or anticipate the result. Moreover, a game may consist of n number of sub-tasks so it is not a good idea to include them in the main framework and are preferred to be abstracted.
Answer:
6 hosts can have IP addresses on the LAN attached to the router interface
Explanation:
Given IP address
=> 192.168.192.10/29
It has a subnet mask of /29 which means it has 3 host bits. This is calculated by subtracting 29 from 32(number of bits in an IPV4)
Since there are 3 host bits, the total number of possible addresses is given by
=> 
= 8 possible addresses.
Out of these 8 possible addresses, the first address will be the subnet id and the last address will be the broadcast address.
Therefore, there are only 6 addresses available for the hosts.

Both spreadsheets and databases, play a part in the daily
operations of many businesses. While you do not necessarily need to choose between spreadsheets and databases, they are often suited to different types of tasks. Understanding the key differences between spreadsheets and databases is vital if you want to make the best use of either or both of them.
Spreadsheets and databases share some characteristics, but they involve different technologies.
Databases generally involve a higher level of technical processing.
