Answer:
Answer A
Explanation:
Answer A, because, metropolitan area network is a network within a city or town and wide area network usually connects many cities. So, both C & D are spread on a wide area.
Explanation:
Both perform almost the same function of storing data, performing numerical calculations, formating cells, and to generate reports.
However, when dealing with data that is short term (requiring less updating) Microsoft Excel is recommended as it provides easy spreadsheet functions. Access on the other hand is a more complex application for data analysis involving constantly changing data values that are long term based. Access allows for efficient data analysis using complex tools such as import module, automated queries etc.
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.
