Cannot find symbol class

I wrote a new class called Pet and I'm trying to get it connected to a pre-written class called Assignment4 for, well, an assignment. However, I can't link the two together. They're saved in the same folder on my computer, so I don't understand the problem. I get the error "cannot find symbol constructor Pet()". Here is the complete code. Thanks in advance for any help.

First Program

Code:

---

public class Pet
{
        private static String petName;
        private static String type;
        private static BirthInfo birth;

        public Pet(String petName, String type)
        {
                petName = "?";
                type = "?";
        }

        public String getPetName()
        {
                return petName;
        }

        public String getType()
        {
                return type;
        }

        public BirthInfo getBirthInfo()
        {
                return birth;
        }

        public void setPetName (String pName)
        {
                petName = pName;
        }

        public void setType (String pType)
        {
                type = pType;
        }

        public void setBirthInfo(int date, int month, int year, String place)
        {
                birth.setDate(date);
                birth.setMonth(month);
                birth.setYear(year);
                birth.setPlace(place);
        }

        public String toString()
        {
                return "\nPet Name:\t\t" + petName + "\nType:\t\t\t" + type +
                          "\nBirth Information:\t" + birth + "\n\n";
        }
}

Second program

Code:

---

import java.io.*;    //to use InputStreamReader and BufferedReader
import java.util.*;

public class Assignment4
 {
  public static void main (String[] args)
  {
      // local variables, can be accessed anywhere from the main method
      char input1 = 'Z';
      String inputInfo;
      String name, type, place;
      int date, month, year;
      String line = new String();

      // instantiate a Pet object
      Pet pet1 = new Pet();

      printMenu();

      //Create a Scanner object to read user input
      Scanner scan = new Scanner(System.in);


      do  // will ask for user input
        {
        System.out.println("What action would you like to perform?");
        line = scan.nextLine();

        if (line.length() == 1)
          {
          input1 = line.charAt(0);
          input1 = Character.toUpperCase(input1);

          // matches one of the case statement
          switch (input1)
            {
            case 'A':  //Add Pet
              System.out.print("Please enter the pet information:\n");
              System.out.print("Enter a pet name:\n");
              name = scan.nextLine();
              pet1.setPetName(name);

              System.out.print("Enter its type:\n");
              type = scan.nextLine();
              pet1.setType(type);

              System.out.print("Enter its birth date:\n");
              date = Integer.parseInt(scan.nextLine());
              System.out.print("Enter its birth month:\n");
              month = Integer.parseInt(scan.nextLine());
              System.out.print("Enter its birth year:\n");
              year = Integer.parseInt(scan.nextLine());
              System.out.print("Enter its birth place:\n");
              place = scan.nextLine();
              pet1.setBirthInfo(date, month, year, place);

              break;
            case 'D':  //Display Pet
              System.out.print(pet1);
              break;
            case 'Q':  //Quit
              break;
            case '?':  //Display Menu
              printMenu();
              break;
            default:
              System.out.print("Unknown action\n");
              break;
            }
          }
        else
          {
          System.out.print("Unknown action\n");
          }
        } while (input1 != 'Q' || line.length() != 1);
  }

  /** The method printMenu displays the menu to a user **/
  public static void printMenu()
  {
    System.out.print("Choice\t\tAction\n" +
                        "------\t\t------\n" +
                        "A\t\tAdd Pet\n" +
                        "D\t\tDisplay Pet\n" +
                        "Q\t\tQuit\n" +
                        "?\t\tDisplay Help\n\n");
  }
}

PS the BirthInfo references are for another class that I wrote, but there don't seem to be any problems linking it with the other programs.

Read teh error message very carefully. How many parameters does your Pet constructor expect? How many parameters are you passing it?

That is saying that you don't have a Pet constructor that takes no arguments. As written the constructor you do have requires name and type arguments. (although I don't know why. what is that constructor supposed to do exactly?)

Ah yes, not sure why I added those arguments in there. I took them out and everything seems to be working fine. Thank you!

In future please try to read and comprehend what the error message says. This one was relatively easy to understand.

Another thing you might want to think about: what is petName in the Pet class supposed to represent? Something static (ie common to pets as a whole)?
