Question
I need to incorporat reading data from a file and writing the output to a file to this program I've already completed. This program will use the Java capabilities of inheritance to accomplish this. Just need the code that would make it read and write with files please

Explanation / Answer
That's fairly straightforward. Scanner is fine for taking inputs, but here's what I usually use for outputting to a file: public void writeOutput() throwsIOException { FileWriter f= new FileWriter("filename.txt"); BufferedWriter b= new BufferedWriter(f); b.write("NAME: " + firstName + " " + lastName+" "); b.write("CREDITS: " + creditsEnrolled+" "); b.write("ADDRESS: " + address+" "); //etc... // the extra is for new lines. b.close(); } remember to import java.io.* as well.
