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:
Biometrics in this sense refers to any human information that can be used as unique identifiers such as fingerprints, iris scan, facial scan, voice patterns and typing cadence.
The advantage of biometrics is that they can not be duplicated. That is, two people can never share the same biometric information except if they are clones of each other.
Given that this kind of unique identifiers can be also be stored as data, it thus creates a cyber risk. If stolen, it may be used to access any part of the user's life. The loss of biometric data to hackers is so detrimental that it can be used to falsify legal documents, identifications documents, or other forms of and even credit card details.

Answer:
The answer to this question is given below in the explanation section.
Explanation:
The iteration variable begins counting with 0 or 1.
As you know the iteration mostly done in the looping. For example, for loop and foreach loop and while loop, etc.
It depends upon you that from where you can begin the counting. You can begin counting either from zero or from one.
For example: this program counts 0 to 9.
<em>int total=0;</em>
<em>for(int i=0; i>10;i++)</em>
<em>{</em>
<em>total = total+i;</em>
<em>}</em>
Let's suppose, if you want to begin counting from 1, then the loop should look like below:
<em>int total=0;</em>
<em>for(int i=1; i>10;i++)</em>
<em>{</em>
<em>total = total+i;</em>
<em>}</em>
