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

Intellij Idea Cannot Resolve Symbol Java
just like you, helping each other. Join them; it only takes a minute: Sign up Getting “cannot find Symbol” in Java project in Intellij up vote 19 down vote favorite 3 I make this call to a http://c2.com/cgi/wiki?CannotResolveSymbol static singleton instance from the class "GameManager.java". HUD.getInstance().update(timeDelta); HUD.java contains the HUD class as well as two other related classes, HUDTextElement and HUDElement. All the classes 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 http://stackoverflow.com/questions/12132003/getting-cannot-find-symbol-in-java-project-in-intellij 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 down vote This is likely to be your ../src folder is not marked as a "source" folder in Intellij IDEA, so it doesn't know to look there to find your class. You can right click the folder in the project explorer and choose "mark as source folder" to fix this. share|improve this answer edited Aug 26 '12 at 17:02 answered Aug 26 '12 at 16:54 Paul Sanwald 5,38512242 1 is a possiblity, but wouldn't 2 not give him an error saying it couldn't find HUD, but rather an error saying it doesn't have getInstance/update m

Nick Garcia Greenhorn Posts: 15 posted 7 years ago Hello, So, in the middle of one of my homework assignments, I start getting this error in http://mindprod.com/jgloss/compileerrormessages.html relation to the scanner class. I thought it might be an error in my code, but I couldn't find any. So I made a completely new project that would simply test cannot resolve out using the scanner class. No dice. I don't know what I'm doing wrong here. I've looked through the API in relation to the Scanner class and everything seems to check okay. import java.util.Scanner; public class ScanDemo1 { public static void main(String[] args) { Scanner sc = new Scanner(System.in); String input = sc.next(); System.out.println(input); } } When this runs, the command prompt shows: cannot resolve symbol C:\java\projects>javac ScanDemo1.java ScanDemo1.java:1: cannot resolve symbol symbol : class Scanner location: package util import java.util.Scanner; ^ ScanDemo1.java:7: cannot resolve symbol symbol : class Scanner location: class ScanDemo1 Scanner sc = new Scanner(System.in); ^ ScanDemo1.java:7: cannot resolve symbol symbol : class Scanner location: class ScanDemo1 Scanner sc = new Scanner(System.in); ^ 3 errors C:\java\projects> I don't really understand where the compiler is having trouble. Any suggestions? NOTE: When posting this, I realized the arrows wouldn't point to what I was seeing, and would instead go to the beginning of the line. I made the letters that the arrows were pointing at BOLD so that you'd see what I was seeing. Except, on the third arrow, I tried making the equals sign (=) bold, but that didn't seem to do much. So, on the third error, the arrow is pointing at the equals sign. Thanks a ton! Carpe diem, because every day is worth living to its fullest.
