I want to pass the ArrayList <String> variable, but I get an error.

private ArrayList<String>list=new ArrayList<String>();;

public test()
{
   list.add("first";
   list.add("Second");

   receive(list); //eclips show here as red and different types
}

public receive (ArrayList<String>list_test)
{
   for(i=0;i<list_test.size();i++){
      System.out.println(list_test.get(i));
   }
}
