My class only compiles in Java 1.6 and not in Java 1.5

Question

Hi, my java class wont compile in java 1.5, it only compiles in Java 1.6. How can i compile the following?
import java.util.*;
public class ShoppingBasket
     Vector products;
     public ShoppingBasket() { products = new Vector(); }
     public void addProduct(Product product)
     boolean flag = false;
     for(Enumeration e = getProducts(); e.hasMoreElements();)
          { Product item = (Product)e.nextElement();
               if(item.getId().equals(product.id))
               {flag = true; item.quantity++; break; }
          if(!flag){ products.addElement(product);}
     public void deleteProduct(String str)
          for(Enumeration e=getProducts();
          e.hasMoreElements();)
          { Product item = (Product)e.nextElement();
               if(item.getId().equals(str))
               {products.removeElement(item); break; }
     public void emptyBasket(){products = new Vector();}
     public int getProductNumber(){ return products.size();}
     public Enumeration getProducts() { return products.elements(); }
     public double getTotal()
     Enumeration e = getProducts();
     double total; Product item;
     for(total=0.0D;e.hasMoreElements();     total+= item.getTotal())
     {item = (Product)e.nextElement(); }
     return total;
}It should link with a class called Product which compiles fine... the errors i get are below:

ah, so should i put the classes into the folder which the classpath is assigned to?More likely you should assign your classpath to whatever folder your classes are in.
Put your files where they make sense, and then fill in classpath accordingly:
javac -classpath classpath MyFile.java(I think, it's been a while since I compiled from the command-line, see http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/javac.html)
