Ok I have a list of words that I need to have checked. How doI get it to check the words in the list and if the string that isbeing read has a keyword in it increase a counter likecounter++;

Explanation / Answer

You have ScannerwordFile = new Scanner(newFileReader(fileName)); For every word you read in from the file, youneed to check if it's contained in your keywords set. int counter = 0; while(wordFile.hasNext()) { if(set.contains(wordFile.next())) { counter++; } } // output if(counter>0) { System.out.println(counter+" keywords found infile."); } else { System.out.println("Nokeywords were found in file!"); }
