Consequently, the most common occurrence of this error is when there is a reference to an undeclared variable. When the Java compiler encounters a use of an identifier which it cannot find in the symbol table, it raises the cannot find symbol error. Besides the naming, there is no difference between what these terms stand for.Ĭannot Find Symbol Error Examples Undeclared variable out-of-scope references to variables and methods Ĭannot Find Symbol vs Symbol Not Found vs Cannot Resolve SymbolĪs different Java compilers use slightly different terminology, the cannot find symbol error can also be found under the terms symbol not found and cannot resolve symbol.missing variable and method declarations.The most common triggers for the cannot find symbol compile-time error include: “location”-the specific class in which the identifier has been referenced.“symbol”-the name and type of the referenced identifier and.The message produced by the compiler for the cannot find symbol error includes two additional fields: While there are multiple ways and reasons this can occur, they all boil down to the fact that the Java compiler is unable to find the symbol associated with a given identifier. ![]() Install the Java SDK to identify and fix exceptions Cannot Find Symbol ErrorĪs its name implies, the cannot find symbol error refers to a symbol which cannot be found. Given a global variable declaration like final double ratio the corresponding symbol would then be. Ī simplified representation of a symbol table entry (or simply, a symbol) in Java has the following format. Symbol tables are also used for code generation and optimization. When uses of these identifiers are encountered in the source code, the compiler looks them up in the symbol tables and relies on this information for things such as verifying that a variable has been declared, determining the scope of a variable, and verifying that an expression is semantically correct with type checking. ![]() As the declarations of classes, interfaces, variables, and methods are processed, their identifiers are bound to corresponding entries in the symbol tables. This information is entered into the symbol tables during lexical and syntax analysis and is used in the later phases of compilation. No errors occur, and my code still works as it should, but I would like to know what I did to make this happen and if it will have any longterm repercussions.Symbol tables are an important data structure created and maintained by compilers to store information associated with identifiers in a given source code. The text in the middle is what bothers me. jGRASP wedge2: exit code for process is 0. jGRASP wedge2: working directory is platform id is 2. ![]() C:\Program Files\Java\jre6\lib\ext\QTJava.zip C:\Program Files\jGRASP\extensions\classes". C:\Program Files\jGRASP\jUnit\junit4.7\junit-4.7.jar. So I don't know what I did exactly to make this happen, but I compiled my code one day and this is what printed out while compiling:
