Please rectify this error...and tell why the heck it is coming??

Do you have more than one GameHelper.java classes floating around? Have you compiled the GameHelper.java file before using it?

Also, when posting code here, please use code tags so that your code will retain its formatting and thus will be readable -- after all, your goal is to get as many people to read your post and understand your code as possible, right?

To do this, highlight your pasted code (please be sure that it is already formatted when you paste it into the forum; the code tags don't magically format unformatted code) and then press the code button, and your code will have tags.

Another way to do this is to manually place the tags into your code by placing the tag [code] above your pasted code and the tag [/code] below your pasted code like so:

[code]
  // your code goes here
  // notice how the top and bottom tags are different
[/code]

Welcome to the Ranch! Please be sure to use code tags when posting code to the forums. Unformatted or unindented code is extremely hard to read and many people that might be able to help you will just move along to posts that are easier to read. Please click this link ⇒ UseCodeTags ⇐ for more information.

Properly indented and formatted code greatly increases the probability that your question will get quicker, better answers.

thnks pete...i'm new to this forum...so missed these finer technicalities..

And yes, i've compiled the GameHelper.java individually too...and no error was reported..and there is no other GameHelper.java hanging around..

I cant understand why "SimpleDotComTester" is not able to access "getUserInput()" as i have declared that under "public" specifier...

HELP HELP!!

It looks like the method is declared as getUserlnput(), while it is called as getUserInput().... notice that the two names are not the same.

Thanks a lot mate...i found it...

[David Patrzeba]

Your call is:

h.getUserInput("string");

however in the GameHelper class you define that function as:

public String getUserinput(String Prompt);

Look at the "i's" i != I.

Thank you all!!

Thanks David for your detailed solution...

[Rob Spoor]

Almost right David. It was an l (lowercase L), not an I.
