Yet another Cannot Resolve Symbol

[Gabinka]

Hi, folks. I'm just at the beginning stages of learning Java, using a book: Java and XML: Your visual blueprint for creating Java-enhanced Web programs.

It's got a nice layout: some info at the top of the page, examples of text editors with code or command prompt with commands on the bottom.

I'm on Chapter 3, where I created an object (AuthorInformation) and it complied fine after I changed the Class to class on the very first word.

Then the book has me "instantiate" the object. It says to create a standalone program that instantiates the object.

So I follow that code precisely in my text editor.

This is what my first object looks like in code:

class AuthorInformation {
String EmailAddress() {
String message = "xxxxxxx@gmail.com";
return message;
}
}

Then my second, following exactly allong with the book:

class go {
public static void main(String[] args) {
AuthorInformation object1 = new AuthorInformation();
System.out.println(object1.EmailAddress());
}

}

Both of these are in the same directory on my computer (BookPractice). As I mentioned the first compiled fine (AuthorInformation.class). The second (go.java) will not. Javac constantly says Cannot resolve symbol and points to the capital A of AuthorInformation in both places it's used.

I've done the -classpath thing, though I don't quite get it. I have put the j2sdk1.4.0 path in my computer's path. So javac is in J:\Programming\j2sdk1.4.0\bin and I use javac j:\workspace\BookPractice\go.java as my command and get the above error.

I've checked and double-checked. It's just like the book shows. I've done javac -classpath .;J:\workspace\*.java;j:\workspace\BookPractice\*. java

What am I doing wrong? I'd really like to get past this so that I can move on with learning.

Do I need to put my files in a separate folder structure? Is this book just too outdated so that I need slightly different code? I could really use a coach here.

Thanks

works fine for me.

I suppose you use and outdated version of the JDK, download a new one ^_^
1.6.0_10 is what I have, and mine already is outdated :p

Anyway, I don't know what code you use to compile+run, but I use this:

@echo off
"C:\Program Files\Java\jdk1.6.0_10\bin\javac" *.java
java go
pause

I'm not doing compile+run, just compile. I'll try and run it once I know it compiles.

I will download a newer JDK if someone will let me know which one. There's Java SE, Jave EE.... etc. Send me a link to a specific download and I'll be glad to download it.

Thanks

I don't know if this matters here or not, but do your classes use proper package statements?

[Gabinka]

I have no idea. I'm really at the beginning of this. I typed exactly what they put in the book. Then say say compile. I try and I get an error.

I don't even know what proper package statements are.

ok the problem is with ur classpath....enter this:

javac -classpath . j:\workspace\BookPractice\*.java

edit: install new version of JDK to avoid this problems
