Java 1.4.2 - Reading Files

Question

I am trying to read a simple file and then a file which the user is supposed to select. I keep on getting the following error though:

Readzilla.java:3

Answer 1

Your problem is this line:

line = read.FileReader(newDoc);

There is no method named FileReader on the class BufferedReader, which is how the compiler is interpreting that line. FileReader is itself a class, and it looks like you're trying to open a new file for reading. Thus, you'd want to say something like:

BufferedReader doc = new BufferedReader(new FileReader(newDoc));

After that, you'd want to replace

line = read.readLine();

with

line = doc.readLine()

because that's how you'd read from the document referenced by the BufferedReader doc.

Additionally, you have a problem here (twice that I see):

loop == "Y"

In Java, == is reference equality only. You absolutely want value equality here so say:

"Y".equals(loop);

This is a common mistake; == as reference equality only was a poor design decision IMO.
