[svaidya]

Hi
I am tryingt o compile a bunch of .java files and a package created linkList.But keep getting the runtime error:
Exception in thread "main" java.lang.NoClassDefFoundError: LinkListTest (wrong n
ame: linkList/LinkListTest)

The LinkListTest has the main in it.this class is part of the linkList package.

Thanks

I am tryingt o compile a bunch of .java files and a package created linkList.But keep getting the runtime error:

So are you trying to compile or run?

If you are trying to run the program then there is something wrong with the command you are using. It would be a good idea to say just what that command is and how it relates to the location of the various .class files involved.

A typical invocation of java.exe would look like:

c:\whereever > java -cp . linkList.LinkListTest

where "wherever" is the directory containing the linkList directory.

Got:
Unrecognized option: -cp.linkList.LinkListTest
Could not create the Java virtual machine.

Put spaces in between, as in: java<space>-cp<space><dot><space><your class name>, just as Pbrockway2 did ...

Hi

C:\Users\Manish\Desktop\elance\example>java -cp . linkList.LinkListTest

Is the absolute path of your file: C:\Users\Manish\Desktop\elance\example\linkList\Li nkListTest.class ?
And does the source of that class contain a line "package linkList;"?

kind regards,

Jos

the path is C:\Users\Manish\Desktop\elance\example -> the example folder has LinkListTest.java there is no folder linkList.yes the files have the line package linkList.Should I make a folder linkList and put the files in them?

Yes, as Pbrockway2 already suggested ...

kind regards,

Jos

ps. the javac compiler has a flag; if set it does that for you.
