Question

In Java how can I take the data of my file on my display screen?
I want to use data in my file and also want that data to be displayed on my output screen when I execute my program. Can any body please help by providing me such example in Java language. Thank you!

A modified version of this example:

import java.io.*;
class Demo {
    public static void main( String [] args ) {
        try { 
            BufferedReader in = new BufferedReader(new FileReader("youFile.txt")); 
            String str; 
            while ((str = in.readLine()) != null) { 
                System.out.println( str ); 
            } 
            in.close(); 
        } catch (IOException e) {}     
    }
}

This is not precisely a “best practice” demo ( ie You should not ignore exceptions) , just what you needed: take data from file and display it on the screen”

I hope you find it helpful.
