I'm saving and running both the files in the same directory and the .class files are being generated in the same folder. I tried the -classpath option as well but didn't work. I'm compiling these files from the windows cmd when tried in Eclipse it is working fine. Also I tried compiling all the files at a time in that folder using javac *.java this is generating all the required .class files without any error but iam unable to figure out why this is not so when compiled individually. java share|improve this question edited Feb 1 '12 at 11:30 Buhake Sindi 56k15111178 asked Feb 1 '12 at 11:09 Galaxin 2201617 add a comment| 5 Answers 5 active oldest votes up vote 2 down vote accepted Besides what Binyamin said, make sure that the current directory is in the classpath.

What does a "Cannot find symbol" error mean? Firstly, it is cannot find symbol 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 sensitive. Perhaps you used underscores inapprop

TestUserInterface.java:5: cannot find symbol symbol: class UserInterface location: class projects.web.TestUserInterface UserInterface ui = new UserInterface(); I have two classes: UserInterface and TestUserInterface. Both are in the same package. To compile and run them I use the following cmds respectively: Code: javac -d ..\classes projects\web\TestUserInterface.java Code: java -cp ..\classes projects.web.TestUserInterface Following is the code for both classes: Code: package projects.web; import java.awt.*; import javax.swing.*; public class UserInterface extends JFrame{ JPanel menuPanel = new JPanel(); JPanel contentPanel = new JPanel(); JPanel selectionPanel = new JPanel(); JButton save = new JButton("Save"); JButton addFiles = new JButton("Add"); public UserInterface(){ super("File Upload"); setSize(500, 500); menuPanel.add(addFiles); selectionPanel.add(save); setLayout(new BorderLayout()); add(menuPanel, BorderLayout.NORTH); add(contentPanel, BorderLayout.CENTER); add(selectionPanel, BorderLayout.SOUTH); } // end constructor } // end UserInterface clas Code: package projects.web; public class TestUserInterface{ public static void main(String[] args){ UserInterface ui = new UserInterface(); } } // end TestUserInterface clas
