Suppose I have declared 2 classes as public in the same file then compilation does not take place ? Why?

Hi,

Welcome to JavaRanch!

The simplest answer is because that's the rule: there can only be one public top-level class or interface per file.

If you need an explanation: it's just because it makes it easier for the compiler to find the source for a given class if it's in a file with the same name as the class.
