How to display the contents of a text file on the command line?

Question

I realize I need to utilize classes from the java.io.* package, but I don't know which ones to use exactly. This is what I would like to do in a nutshell:
public static void main(String[] args) throws IOException {
File inputFile = new File( <path to the file>);
// code that reads data from the above file and is able to
// append it to  a string object or display it on the command
// line (System.out.println)
}Thanks for your time!

Answer 1

It's pretty easy. Here's a little example that reads a file, stores it in a string, and prints it to the command line.
import java.io.*;
public class OpenFile {
     public static void main(String args[]) {
          try {
               File fileToOpen = new File("something.txt");
               FileReader fileIn = new FileReader(fileToOpen);
               BufferedReader br = new BufferedReader(fileIn);
               String fileContent = new String();
               String line;
               while ((line = br.readLine()) != null) {
                    fileContent += line + "\n";
               System.out.println(fileContent);
               br.close();
          catch (IOException e) {
               System.out.println("Exception: " + e);
}Good luck,
