Question

How to search for a specific word in a text file containing word texts and return its frequency or appearance?

Answer 1

Using a scanner:

String text = "Question : how to search for a particular word in a " + "text file containing texts of words and return its " + "frequency or occurrences ?"; String word = "a"; int totalCount = 0; int wordCount = 0; Scanner s = new Scanner(text); while (s.hasNext()) { totalCount++; if (s.next().equals(word)) wordCount++; } System.out.println("Word count: " + wordCount); System.out.println("Total count: " + totalCount); System.out.printf("Frequency: %.2f", (double) wordCount / totalCount); 

Conclusion:

 Word count: 2 Total count: 24 Frequency: 0.08
