Hey there guys, I am having a problem with with my ReadFile constructor. First of all the class that I am placing the constructor in is in a different package. I have imported the package to the class that I am placing the constructor But I still get an error (at the red). Please take a look at it for me guys and gals.

Take a look at the java page on FileReader() which lists 3 possible constructors.

http://java.sun.com/j2se/1.4.2/docs/api/java/io/FileReader.html

I do not see a constructor that can be used without passing a parameter to the constructor. i.e i don't see new FileReader();

maybe this constructor they list there would work:

FileReader(String fileName)
Creates a new FileReader, given the name of the file to read from.

Then I would say the OP is confused by the lack of a no argument constructor. The no argument constructor is only automagically present if the class does not provide any other constructors. I.e., since FileReader has other constructors, the compiler would not provide a no argument constructor automagically, and the only reason one would be there is if someone had explicitly written one.
