my project is in “\BankPrj” folder
It has
(1).com folder
(2)Account.java,Customer.java,TestBanking.java files
(3) main class is in TestBanking.java
this is the error..

this is my complete project
https://docs.google.com/folder/d/0BzMe2Ya7vhrAem5rcEljc3k1cFE/edit
pls correct the errors.
i executed TestBanking.class from test folder itself.
Your package is com.mybank.test
The way you should invoke is that go to Folder BankPrj.
now do
java -classpath . com.mybank.test.TestBanking
This should work now.
Remember, you cannot go into the leaf of the folder to execute your class. You should always stay at the root (when using the package) and execute with fully qualified package name and the class name to execute it.
Hope this helps!
