Comparable interface problem.

i wrote a small code to use the Comparable interface but am getting an error..please someone tell me where i went wrong.

import java.util.*;
class DvDinfo implements Comparable<DvDinfo>
{
	String title,genere,actor;
	DvDinfo(String t,String g,String a)
	{
		title=t;
		genere=g;
		actor=a;
	}
	public String toString()
	{
		return title+" "+genere+" "+actor+" \n";
	}
	public int compareTo(DvDinfo d)
	{
		return title.compareTo(d.getTitle());
		
	}
	public String getTitle()
	{
		return title;
	}
}

public class DVDinfo{
	public static void main (String[] args) {
	
    DvDinfo d1=new DvDinfo("aag","action","el");
    DvDinfo d2=new DvDinfo("pani","comedy","el");
    DvDinfo d3=new DvDinfo("ben10","action","am");
    ArrayList<DvDinfo> ar= new ArrayList<DvDinfo>();
     ar.add(d1);
     ar.add(d2);
     ar.add(d3);
     Collections.sort(ar);
     System.out.println(ar);
     
}
}

output==E[color=red]xception in thread "main" java.lang.NoClassDefFoundError: DvDinfo (wrong name: DVDinfo)[/color]

i dont understand why the jvm isnt able to find the DvDinfo class?

Check the code again there are two DVDinfo class definitions! And UseCodeTags when you post codes!

Sorry...this was my second post here

i understood my mistake in naming the classes :

thanks for helping

So, did you solve the problem?

Absolutely, the problem is solved

generics and collections are heck of a topic so i have to move slowly and in future i will be posting even more queries

thanks again for helping. Have a nice day

You are Welcome!
