In JAVA does file name and class name must be same or it is recommended?

Question

why so?

Answer 1

well then if I write two classes in a single java file what should I give the file name?

Answer 2

@ashwaghosh you have to name .java to that class which will have main method. compiler will automatically make. class file for all classes that you have.

Answer 3

Get file name then run method main()

Then example
I named one file with "Itaiyo.java"
Ah....what kind of that file?
Then compile....*wait 1 hour*
Run Itaiyo.class
This Itaiyo.class will run "new Itaiyo().main(*Some arguments which idk how to read*)"
#(I guessed all of that)
