Quizplus · Accepted Answer

To read all words from a text file, we need to check whether there are more words to read or not. The choice C (in.hasNext()) checks whether there are more words available to read or not. So, we can use this method to read all words from the text file. The choices A (in.getNext()) and D (in.peek()) are not the valid methods to read words from a text file. The choice B (in.nextWord()) is not a valid method in Java.
