I have written two interfaces: Class and Game. Interface CLASS is supposed to extend interface GAME. Here are the two interface sources: package Impl; public interface Game { //METHODS AND VARS } package Impl; public interface Class extends Game { //METHODS AND VARS } Now, when I try to compile the second interface, I get the following error class.java:4: cannot find symbol symbol: class Game public interface Class extends Game
Java Error Cannot Find Symbol File
^ My Game class is compiled and the class file is in the same directory as both java files. I have not been able to find a solution. Does anyone have any ideas? java compiler-errors share|improve this question edited Oct 11 '10 at 3:21 James McNellis 244k46708846 asked Oct 11 '10 at 3:19 Jay 21112 add a comment| 2 Answers 2 active oldest votes up vote 8 down vote Class names are case sensitive. It is possible that you have created an interface called game, but you refer to it in your Class interface declaration as Game, which the compiler cannot find. However, there is another chance that you are compiling from within your Impl package. To do this, you will need to reference your classpath such that the compiler can find classes from the base of the package structure. You can add a -classpath .. arg to your javac before the class name: javac -classpath .. Class.java Alternatively, you can do what is more common, compiling from the root of your package structure. To do so, you will need to specify the path to your Class file: javac Impl\Class.java you can always add a -classpath . to be clear. share|improve this answer edited Oct 11 '10 at 3:53 answered Oct 11 '10 at 3:42 akf 28.9k65986 Thank you.

If it can't find what an identifier refers to (e.g., there is no declaration statement for a variable) it cannot complete the compilation. This is what the cannot find symbol error message is saying, it doesn't have http://stackoverflow.com/questions/3903330/cannot-find-symbol-compile-error enough information to piece together what the Java code wants to execute.Possible Causes:trying to use a variable without declaring it.misspelling a class or method name (remember, Java is case sensitive).the parameters used do not match a method's signature.the packaged class has not being referenced correctly using an import declaration.Examples: The following code: System.out.prontln("The perils of mistyping.."); will cause a cannot find symbol error because the System.out class does not have a method called “prontln”: cannot find symbol http://java.about.com/od/cerrmsg/g/Definition-Cannot-Find-Symbol.htm symbol: method prontln(jav.lang.String) location: class java.io.printStream The two lines below the message will explain exactly what part of the code is confusing the compiler. continue reading below our video 9 Tips to Extend Your Phone's Battery Error Message Glossary:# A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Show Full Article Related Compile-time Error Understanding 'Overloading' In Java Parameter Statement More from the Web Powered By ZergNet Sign Up for Our Free Newsletters Thanks, You're in!
