Hi!
You should take a look at Sun's Java Tutorial.

Here is an example (from the link above) to copy a file:

import java.io.*;
 
public class Copy {
    public static void main(String[] args) throws IOException {
File inputFile = new File("farrago.txt");
File outputFile = new File("outagain.txt");
 
        FileReader in = new FileReader(inputFile);
        FileWriter out = new FileWriter(outputFile);
        int c;
 
        while ((c = in.read()) != -1)
           out.write(c);
 
        in.close();
        out.close();
    }
}
