I am facing an error "MyBook.java:35: error: class Solution is public, should be declared in a file named Solution.java public class Solution ^ 1 error"

why? and is the code right?

Code:

public class MyBook extends Book {int p;

 MyBook(String title,String author,int price)
    {
     super(title,author);

     this.p=price;

}
void display()
    {
    System.out.println("Title: "+title);
    System.out.println("Author: "+author);
    System.out.println("Price: "+p);
}

}
