I am attempting to create a program that reads two text files, which both contain thousands of words. I need to be able to select 10 words at random from each file and store them in an array of four string lists. I have created the following code so far, however this only selects one word from each file, not 10. How can this be done - preferably using an if statement?
import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.Random;
import java.util.Scanner;
public class RandomWordGenerator {
public static void main(String[] args) throws FileNotFoundException {
public class RandomWordGenerator {
public static void main(String[] args) throws IOException {
Path outputFile = Paths.get("output.txt");
ArrayList<String> randomWords1 = randomWordsFromFile("textfile1.txt", 10);
ArrayList<String> randomWords2 = randomWordsFromFile("textfile2.txt", 10);
OutputStream outputStream = new BufferedOutputStream(Files.newOutputStream(outputFile, CREATE));
System.out.println(randomWords1);
System.out.println(randomWords2);
outputStream.flush();
for (int i = 0; i < randomWords1.size(); i++) {
outputStream.write(randomWords1.get(i).getBytes());
}
for (int i = 0; i < randomWords2.size(); i++) {
outputStream.write(randomWords2.get(i).getBytes());
}
outputStream.close();
}
private static ArrayList<String> randomFromFile(String fileName, int count) throws FileNotFoundException {
Scanner scanner = new Scanner(new File(fileName));
ArrayList<String> words = new ArrayList<>();
while (scanner.hasNext()) {
words.add(scanner.next());
}
return randomFromWords(words, count);
}
static private ArrayList<String> randomFromWords(ArrayList<String> words, int count) {
ArrayList<String> randomWords = new ArrayList<>();
for (int i = 0; i < count; ) {
int random = new Random().nextInt(words.size());
if (randomWords.add(words.get(random))) {
i++;
}
}
return randomWords;
}
}
