Parameter transmission problem

Question

Hello! I have the following two classes:
public class VeterinaryReport
int dogs;
int cats;
String name = new String();
public int GetAnimalsNo()
return dogs + cats;
public void DisplayStatistics()
System.out.println("Total number of animals is "+ GetAnimalsNo() + ".");
System.out.println("The owner of the animals is "+ name + ".");
return;
import java.io.Console;
class VeterinaryTest
        public static void SetName(String name)
         Console cons;
      if ((cons = System.console()) == null)
      System.err.println("No console.");
      System.exit(1);
      String login = cons.readLine("Enter name for veterinary: ");
         name = login;
         return;
        public static void main(String[] args)
           VeterinaryReport vr = new VeterinaryReport();
           vr.cats = 20;
           vr.dogs = 40;
           SetName(vr.name);
           vr.DisplayStatistics();
           return;
}, and the problem is no names are displayed at the call of DisplayStatistics, like this: "The owner of the animals is ."
Inside the function, everything works, so I guess it's something of parameter transmission that I don't know about.
can anyone see what goes wrong?
Cheers

The problem is that the SetName method is in the VetTest class and not the VetReport class. There is absolutely no connection between the name variable in the SetName method and the VetReport class. So that means that whatever changes you make to the name variable in SetName has no effect on name in VetReport. When you print out the data name in VetReport is still an empty string and that is what you see on the screen: nothing.
