![]() ![]() Note that not every "correction" is correct. Then finally you work out what correction you need to make to your source code to do what you want. Then you think about what your code is supposed to be saying. Figure out why the compiler is saying that it cannot find the symbol see above!.Identify which symbol that the error message is talking about.Look at the line in the file indicated by the compilation error message. IS server 4.6 developer 4.6 JDK 1.4.1 w2k Thanks -V The source was saved, but was not compiled due to the following errors: C:\Program Files\webMethods\IntegrationServer4\packages\Default\code\source\Bitterroot.java:42: cannot resolve symbol symbol : variable StringGSGacknumber location: class Bitterroot String.Generally speaking, you start out by figuring out what caused the compilation error. There are some other more obscure causes too. Or better still use a Java build tool e.g. The simple answer is to compile Foo and Bar together e.g. If you have never compiled Bar and you run javac Foo.java, you are liable to find that the compiler can't find the symbol Bar. For example, if you have classes Foo and Bar where Foo uses Bar. You might simply have forgotten to compile or recompile some other class. There is another reason why the compiler might not find a symbol if you are compiling from the command line. What he meant to write was this: int res = tmp * (a b) In the example I came across, the programmer had actually left out an operator. The previously declared tmp is in the namespace for variables, not the namespace for methods. The compiler will look for a method called tmp, and won't find one. ĭespite the previous declaration, the tmp in the tmp(.) expression is erroneous. Here is another example of "Cannot find symbol" error that is caused by a typo. So, in your Choice class, make sure that getText() is spelled exactly like that and the visibility modifier is public. Operators and other non-alphanumeric tokens: like , =, block is NOT the body of the for loop, and therefore the previous declaration of i in the for statement is out of scope in the block. In order to resolve the 'symbol' or method name, it must be spelled the same and not private.Literals: like true, false, 42, 'X' and "Hi mum!".import So make sure for the next time, you’ve imported all the classes that you’re using in your program. Keywords: like class, while, and so on. But if you’re using a simple text editor then you have to manually write a line at the top of your java file. ![]() Your Java source code consists of the following things: It means that either there is a problem in your Java source code, or there is a problem in the way that you are compiling it. What does a "Cannot find symbol" error mean?įirstly, it is a compilation error 1. (Different Java compilers are written by different people, and different people use different phraseology to say the same thing.) 1. ![]() "Cannot find symbol", "Cannot resolve symbol" and "Symbol not found" all mean the same thing. Is there any difference between these errors? The overall structure of the code was copy pasted from a previous program that I wrote, so the file reading should work properly, but when it's inside of the method that is outside the main, the compiler doesn't know what to do with those 3 methods that show up in the error messages.0.
