Class not found ! HELP !

Question

Dear Java People,
Hello how are you today ?
I have an error in my Support System class that says
"class InputReader not found" in the following lines of code:
private InputReader reader;
and also this error is found in the below line of code:
reader = new InputReader();
below is the class where the error originates
and the other classes also
thank you in advance
Stan

i looked at the code quickly but noticed that you declare you class as:
public class inputReader
but used:
private InputReader reader;
java is case sensitive so I (uppercase) is different from i (lowercase).
