this is the code I have. I am printing words with only 5 letters from a document named: words.txt", I am taking those words of 5 letters, and creating a new file named: "five.txt".
but when I open the file, the words are not there. here’s my code:
public static void main(String[] args) throws IOException
{
try (Scanner in = new Scanner("words.txt");
PrintWriter out = new PrintWriter("five.txt");)
{
while (in.hasNext())
{
String word;
word = in.next();
if (word.length() == 5)
out.println(word);
}
}
catch (IOException e)
{
System.out.println("Could not read the words: " + e.getMessage());
return; // Exit main now
}
}
>Solution :
new Scanner("words.txt")
That doesn’t do what you think it does. That will make a scanner for the input ‘words.txt’. Not, ‘the contents of the file "words.txt"’. No, literally, ‘words.txt’. Which has one token, of length 9, which is "words.txt".
You want new Scanner(new File("words.txt")).
