Answer / sarabjit singh
when a code is to wriiten in a single file, no matter how
many number of classes being used, the de-facto standard
for naming the file is <ClassName>.java,
where <ClassName> is the name of the class containing the
main function().
Hence in our case, if class A is having the main() method,
then the file name would be A.java.

Answer / mohammad faisal
The most common answer is: it would be the class name
having the main() method.
If you are using multiple classes in a single file than it
doesn't matter how much the number of classes.
But there is a problem for begienners that by what name
should they save the file.
There is something interesting to java:
You can save the program by any name. i.e.,
Let your program is:
class a
{
}
class b
{
}
class c
{
public static void main(String args[])
{
}
}
Now save the file as Amazing_Example.java
Compile the file as:
c:\>javac Amazing_Example.java
c:\>
This compilation is successfull.
Now you can run the program using the name of class having
the main() method. As in our example class c has the main()
method.
i.e.,
c:\>java c
c:\>//Here will be the output of your code.

we run our program with that .class file which having the
public static main() method.
