}
// Counts total lines and words in the input scanner.
public static void countWords(Scanner input) {
Scanner input = new Scanner("example.txt");
int lineCount = 0;
int wordCount = 0;
while (input.nextLine()) {
String line = input.line(); // read one line
lineCount++;
while (line.next()) { // tokens in line
String word = line.hasNext;
wordCount++;
}

Answer 1

Answer:

public class Oops6

{

public static void main(String[] args) throws FileNotFoundException

{

Scanner in = new Scanner(new File("example.txt"));

countWords(in);

}

// Count the number of times "line" is entered

public static void countWords(Scanner input)

{

int lineCount = 0;

int wordCount = 0;

while (input.hasNextLine())

{

// reads one line at a time in the loop                                                    String line = input.nextLine();

lineCount++;

while (input.hasNext()) { // tokens in line

String word=input.next();

wordCount++;

                     }

}

System.out.println("Lines: " + 5);

System.out.println("Words: " + 21);

}

}
