If you have two public classes in a java file what will be the error and how will you remove it?

Hmm, let me see, it is technically perfectly legal to have 2 classes in a single file, as long as one class is an inner class of the other: i.e. public class Stevo{ public class Fun{}}. But if you want two separate classes independent of each other the compiler would scream at you about class is public and should be declare in a file named [className].java. To fix this simply follow the compiler's instructions (shocking! the compiler actually was clear about something) and create a new file with the given name. But sometimes an inner class would be helpful, i.e. an iterator for the Abstract Data Type you are implementing.

Java runtime error - NoClassDefFoundError -- how to remove this error in java programming?
This error means that there was a call to a nonexistent class, but this was not caught by the compiler since the class existed when the file was compiled but was removed before running the .class file. To fix this problem try restoring any files you deleted to the SAME directory as your .class file. This error can also be fixed by changing the Java classpath to point to the locations of your files. The -cp command line option should help.
