Printing a list

Question

Hi
I'm trying to write a method to print a list containing a music records details.an empty string should be used if certain information is not available. this information should then be excluded from the printing i.e. the method should print all non empty strings.
class recordDetailsClass
String recordName;
String recordArtist;
String recordLabel;
public recordDetailsClass(String a, String b, String c)
recordName=a;
recordArtist=b;
recordLabel=c;
public void printDetails()
recordDetailsClass next;
System.out.println("Record Name: " + recordName);
System.out.println("Record Artist: " + recordArtist);
System.out.println("Record Label: " + recordLabel);
} Any ideas?
Thanks

import java.util.*;
class AssessedPracB1
     public static void printList(List L)
      contactDetailsClass nextContact;     
          for (int i=0; i<L.size(); i++)
          nextContact = (contactDetailsClass) L.get(i);
          System.out.println(nextContact);
          System.out.println("=============");     
     public static void main(String[] args)
          List contacts = new LinkedList();
          contacts.add (new contactDetailsClass("M Collin John", "84 Gleban Close", "Super Parcels LTD, Spain" , "02890376198","",""));
          contacts.add (new contactDetailsClass("J Gilbraithe", "1 Gilford Street", "Ian&Sons Tilers LTD, Vietnam" , "02890376198","",""));
          contacts.add (new contactDetailsClass("K Pressman", "92 Glen Avenue", "Tesco LTD, Belfast" , "","02840987392",""));
          contacts.add (new contactDetailsClass("B Strain", "95 Orchard Close", "Mighty Parcels LTD, Portglnone" , "02890376198","",""));
          contacts.add (new contactDetailsClass("M McCanning", "8 The Square", "Patton Road Services, Crossmaglen" , "02890376198","",""));
          contacts.add (new contactDetailsClass("K O'Hare", "19 The Olde Cuff Links", "" , "02838356118","","07778282738"));
          printList(contacts);
class contactDetailsClass
     String name;
     String home;
     String workAddress;
     String homeTel;
     String workTel;
     String mobileTel;
     public contactDetailsClass(String a, String b, String c, String d, String e, String f)
          name=a;
          home=b;
          workAddress=c;
          homeTel=d;
          workTel=e;
          mobileTel=f;
     public void printDetails()
     if(name != null && name.length() >0){
    System.out.println("Name: " + name);
     if(home != null && home.length() >0){
    System.out.println("Home: " + home);
     if(workAddress != null && workAddress.length() >0){
    System.out.println("Work Address: " + workAddress);
     if(homeTel != null && homeTel.length() >0){
    System.out.println("Home Tel: " + homeTel);
     if(workTel != null && workTel.length() >0){
    System.out.println("Work Tel: " + workTel);
     if(mobileTel != null && mobileTel.length() >0){
    System.out.println("Mobile Tel: " + mobileTel);
}This is another one i need to fix which gives the same error, more detailed code so could be easier to fix
