I have just begun to learn java. I read in a book that the Java compiler compiles classes that do not contain a main() method . But java has no way to run these classes . So ,if we type Main instead of main, the compiler would still compile the program . However, java would report an error because it would be unable to find main() method .

What is the difference between the two ?

What I have tried:

I found this in the book Java The Complete Reference by Herbert Schildt

Your question made sense, but the title is so irrelevant.

Java, like most other languages, is case sensitive when it comes to classes, methods, objects etc. So a method called Main is not the same as one called main. You can compile any number of classes independently, and they do not all need to include a static main method. However, you must have such a method somewhere amongst all the classes in order to run the application. The main method is where the program always starts from. You can find lots of good information in The Java™ Tutorials[^].

Java is case sensitive, it means that main and Main are 2 different things.
Main is user (you) defined name, just like any other name you define for your app.
main is language defined, this is the piece of code that is launched when your app is loaded. Note that you can't call main from your code.
