What does a "Cannot find symbol" error mean? Firstly,

it is a compilation error1. 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. Your Java source code consists of the following things: Keywords: like true, false, class, while, and so on. Literals: like 42 and 'X' and "Hi mum!". Operators and other non-alphanumeric tokens: like +, =, {, and so on. Identifiers: like Reader, i, toString, processEquibalancedElephants, and so on. Comments and whitespace. A "Cannot find symbol" error is about the identifiers. When your code is compiled, the compiler needs to work out what each and every identifier in your code means. A "Cannot find symbol" error means that the compiler cannot do this. Your code appears to be referring to something that the compiler doesn't understand. 2. What can cause a "Cannot find symbol" error? As a first order, there is only one cause. The compiler looked in all of the places where the identifier should be defined, and it couldn't find the definition. This could be caused by a number of things. The common ones are as follows: For identifiers in general: Perhaps you spelled the name incorrectly; i.e. StringBiulder instead of StringBuilder. Java cannot and will not attempt to compensate for bad spelling or typing errors. Perhaps you got the case wrong; i.e. stringBuilder instead of StringBuilder. All Java identifiers are case sensi

If it can't find what an identifier refers to (e.g., there cannot find 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 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 cannot find symbol 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 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!

I am not going to post my full code as it is over 3,000 lines long. It is just a personal program I am trying to write to keep track of my personal abilities compared on a scale. For instance, where I can input my bench press weights, 100 meter run time, swimming times, etc compared to a personally defined scale or against the world records for such. Just thought I would mention this as it is not a serious work. Here is the code sections that the error deals with. Error is specifically "cannot find symbol method customValues(int)" and "cannot find symbol method attribValues(int)". I tried declaring in main as public, but it didn't matter (and shouldn't). import javax.swing.*; import java.awt.*; import java.awt.event.*; import java.io.*; public class Attributes extends JFrame { // Initialize array with inventory values double[] customValues = new double[73]; String[] attribValues = new String[73]; ... ... ... else if (e.getSource() == loadProfile) { //Load scale parameters and values from file try { FileInputStream fstream = new FileInputStream("MyAttributes.txt"); DataInputStream in = new DataInputStream(fstream); BufferedReader br = new BufferedReader(new InputStreamReader(in)); String strLine; count = 0; //Read File Line By Line while ((strLine = br.readLine()) != null) { if (count < 74) { //Error message occurs here customValues(count) = Double.parseDouble(strLine); } else { //And here attribValues(count-74) = strLine; } count = count + 1; } in.close(); } catch (Exception e) { JOptionPane.showMessageDialog(frame,"File does not exist"); } //Assign loaded values double variables cBench = customValues(0); cSquat = customValues(1); ... ... ... Any help is much appreciated. I have tried multiple ways of declaring the arrays. Is This A Good Question/Topic? 0 Back to top MultiQuote Quote + Reply Replies To: "Cannot find symbol met
