This applies if you have either no CLASSPATH set, or a CLASSPATH which has '.' (the current directory) in it. Variable namess -- If it is a variable name, you did not declare your java cannot resolve symbol list variable before attempting to use it, or you misspelled it (that includes having the incorrect case). Another possibility is that the variable is in the wrong scope, e.g.: class X { int x=5; } class Y { public static void main(String[] args) { System.out.println(x); //x cannot be resolved //now for a working version: int x=6; System.out.println(x); } } Methods -- On a method name, the same things java cannot resolve symbol println apply as for variable names, plus you may have given the method the wrong parameter types, e.g., calling add(int) where you should have called add(Object). You could also get this error when trying to invoke a constructor that doesn't exist or is not visible, e.g.: class X { private X(int y) { } } X x=new X(5); //this won't work, remove 'private'. X x=new X("Hello"); //this won't work, add a constructor as follows: class X { X(int y) { } public X(String string) { } } X x=new X("Hello"); //this works now. A small point with the above is that instead of just removing 'private' you should probably replace it with 'public'. Constructors -- If you called a constructor with the wrong parameters, you can get a cannot resolve symbol error, but the error will include the word 'constructor'. Check the original constructor to see what you should have used. Check the types of parameter in the API, compared to the types that you used (as reported in the compiler error message). The order of the types should be the same too. -- RickyClarkson CategoryJava View edit of May 12, 2012 or FindPage with title or text search

HUD.getInstance().update(timeDelta); HUD.java contains the HUD class as well as two other related classes, HUDTextElement and HUDElement. All the classes http://stackoverflow.com/questions/12132003/getting-cannot-find-symbol-in-java-project-in-intellij are in the same root path ../src/org/mypackage However, when compiling this java project in IntelliJ I get "cannot find Symbol HUD" on the line I make the HUD.getInstance() call. This exact same code compiles just fine in eclipse, any idea what the problem is? java intellij-idea share|improve this question asked Aug 26 '12 at 16:50 joe 353128 Do you have the HUD class imported in both? –Alex Coleman Aug 26 '12 at 16:53 add a comment| 10 Answers 10 active oldest votes up vote 30 down vote I had the same problem, and turns out I had never completely compiled the fresh project. So right-clicking and selecting Compile'' (shift-cmd-F9 on mac) fixed it. It seems the compile on save does not 'see' non-compiled files. Marking the src folder as source did not help in my case. share|improve this answer answered Mar 6 '13 at 9:13 Sjoerd K 40142 This solved it for me. +1 :) –Babyburger Mar 2 '15 at 19:47 add a comment| up vote 13 d

So your class Stack would conflict with java.util.Stack. And You need to post the exact compiler error you see, that will help us to guide you to the solution Mohamed Sanaulla | My Blog Jesper de Jong Java Cowboy Saloon Keeper Posts: 15513 43 I like... posted 4 years ago 1 What is the exact error message and on which line of your source code does it happen? All the details in error messages are important, and give you exact information where and what is wrong. Read the error message carefully. "Cannot resolve symbol" means that you're using a name (of a variable, method, class etc.) that the compiler doesn't recognize. Looking at your code, I see at first sight that there are errors on lines 9, 10 and 11 of StDemo. If you want to call the pop() method on your class Stack, you'll need to write that as my.pop(), not my.pop.
