pls correct the errors.

i executed TestBanking.class from test folder itself.

回答1:

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!
