Question about public access modifier for a class in Java.

Question

I just started learning about objects and classes in Java. So I made this simple code for practice.

https://code.sololearn.com/cBffP9Q9pd44/?ref=app

I'm using "command prompt" for running my programs.(I know I can use better IDE's ,but I really want/like to *learn* using command...)

The problem I faced here is that when I start my class definion (of class 'Warrior') like
public class Warrior {....
On compilation I get an error message
"class warrior is public, should be declared in a file named Warrior.java"
So why this error ? This doesn't occur if I try on sololearn .

Also private modifier doesn't work...(shouldn't that be by default) It works only when I leave class definitions without any specifiers.like
class Warrior{...
Please help me understand why this happened on command prompt and not on SL.

I'm just getting started and I can't move further without getting clear idea of what I'm currently learning and this is my first code on sl so please give your valuable suggestions.

Thank you... 🙏☺
