Java problem?

Question

when we make public class name same as file name but we cannot make public class name when we write different class name and file name. why?

Answer 1

If you are making a class public in a Java file then the name of the file must match the public class name and you can have only 1 public class in a Java file.

If at all you want to name your file something else then you shouldn't have even a single public class in your Java file.

Program.java

public class Program{
public static void main(String[] args){

}
}

Anything.java

class A{
public static void main(String[] args){

}

class B{
}

Your question isn't clear. This is from what I have understood from the question.

Avinesh thanks a lot 😇😇

Answer 3

Avinesh yes you got it
This is what i was saying but i want to know why we should not make public class in case of different file name and class name

Answer 4

By convention if you make a class public then the file name must match the class name. So if you are going to make a class public and give a different name, then the compiler will throw an error.
