read char words lines

Hello all in java land. I need some help figuring out how to read and display a txt file, the amount of words, the amount of lines and amount of char not including white spaces. I can open the file and display it but i dont have much else. heres what i got thus far...

Code:

---

package hw3;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
public class Hw3 {

        public static void main(String[] args)throws Exception {
                                try {
                                            BufferedReader in = new BufferedReader( new FileReader("file"));
                                          String line;
                                            while ( ( line = in.readLine() ) != null ) {
                                                    System.out.println( line );
                                            }
                    in.close();
                    } catch (IOException e) {
                    e.printStackTrace();
                    }
                   
        }}

First of all, use a Scanner, BufferedReaders don't work well for files, they are more for command line programs. Then, create a while loop that adds the lines to an ArrayList (or Array, but that is far more difficult). Make the loop repeat until there are no lines left. You can then divide the lines into words, and count the total words, characters, and lines.

Basically, you will end up with an ArrayList<String> containing lines, and probably a String[][] containing words.

I'll try to create some sample code for you

Good Luck,

So, you can do part one: reading in the file and displaying it, and now on to the other parts.

Let's start with the line count: How do you think you may be able to count the lines in the file? Any guesses?
