Declaring a class in Java?

Question

I wrote some code that works here on SL Playground; but when I put it in a different compiler, it says I need to connect the class to a file. How do I fix this issue?

"compiler.java:2: error: class Program is public, should be declared in a file named Program.java"

/*####THE CODE####*/

import java.util.Scanner
public class Program

{
public static void main(String[] args) {
Scanner vv = new
Scanner (System.in);
System.out.println("Yes?");
String n = (vv.nextLine());
System.out.print("Ah.. Hello there, ");
System.out.print(n);
System.out.println("!");
}
}

// Output: Yes? Ah.. Hello there, <name>!

Answer 1

File name = class name.
If your class has the name program then your file name should be also program.
