I am starting out running jdk 1.3.1.01 and I am utilizing Walter Savitch's book on Java. While my "Hello World" program compiles & runs fine, the first example in his book utilizes a required class file. (SavitchIn.java) The first tutorial, FirstProgram.java, calls class "SavitchIn" and method "readLineNonwhiteChar", but I get the error; bash-2.03$ javac FirstProgram.java FirstProgram.java:10: cannot resolve symbol symbol : variable SavitchIn location: class FirstProgram answerLetter = SavitchIn.readLineNonwhiteChar(); It seems it cannot find the class file SavitchIn. I thought that could be handled by setting the CLASSPATH variable, but I have tried several settings with no change in result. Walter's book does not cover this, and neither does the Java tutorial I have found for starting with Sun java. I have an idea that the answer here is a simple one... The program follows; (the problem wouldn't be the ^M's would it?) public class FirstProgram^M {^M public static void main(String[] args)^M {^M System.out.println("Hello out there.");^M System.out.println("Want to talk some more?");^M System.out.println("Answer y for yes or n for no.");^M ^M char answerLetter;^M answerLetter = SavitchIn.readLineNonwhiteChar();^M if (answerLetter == 'y')^M System.out.println("Nice weather we are having.");^M ^M System.out.println("Good-bye.");^M ^M System.out.println("Press enter key to end program.");^M String junk;^M junk = SavitchIn.readLine();^M }^M } To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
