Can I compile a java file with a different name than the class?

Question

Is there any way to compile a java program without having the java file name with its base class name.

If so, please explain..

Answer 1

To answer the question take a look at this example:
Create a file Sample.java

class A  {     public static void main(String args[])    {        String str[] = {""};        System.out.println("hi");        B.main(str);     }  }  class B  {     public static void main(String args[])     {       System.out.println("hello");    } }  

now you compile it as javac Sample.java and run as java A then output will be

hi  hello 

or you run as java B then output will be
hello

Notice that none of the classes are marked public therefore giving them default access. Files without any public classes have no file naming restrictions.
