Multiple classes in single file

Question

I\'m having trouble putting multiple classes into a single file. For example, when my file looks like:

public class FirstClass() {}
public class SecondClass(         


        

Answer 1

Just remove public from all other class definition and paste the code into TheaterDemo.java file

public class TheaterDemo
{
    public static void main(String[] args)
    {
        TheaterWindow theaterWindow = new TheaterWindow();
    }
}
//Here class code after removing public

// Here another class code
