    Default newbie help

    Hey guys,

    I'm a java newbie struggling to correct this problem. It's an error mesage I get, don't understand why.

    It's a homework assignment and I have to create Person, Date, SSN objects and run them in main together.

    The error occurs when, in main, I try to create a new Person and plug in first name, last name, etc.

    public class PersonTester {
     
    	public static void main(String[] args) {
     
     
    	Date hermanBday = new Date(11,11,2011);
    	Person Ken = new Person();
    	Person Herman = new Person("Herman", 'H', "Wilson", hermanBday, "111-11-1111");
     
     
    	} //end main
    }//end class

    I get this error message when I compile:

    ----jGRASP exec: javac -g PersonTester.java

    PersonTester.java:8: cannot find symbol
    symbol : constructor Person(java.lang.String,java.lang.String,java.lang .String,Date,java.lang.String)
    location: class Person
    Person Herman = new Person("Herman", 'H', "Wilson", sueBday, "111-11-1111");
    ^
    1 error

    ----jGRASP wedge2: exit code for process is 1.
    ----jGRASP: operation complete.



    Here's the Person class, the error message hints that something is wrong w my constructor (my default constructor seems to work fine)

      public class Person {
     
          private String firstName;
          private char middleInitial;
          private String lastName;
          private Date birthdate;
          private SSN social;
     
     
       //no-arg constructor
          public Person() {
     
             firstName = null;
             middleInitial = '\0';
             lastName = null;
             birthdate = null;
             social = null;
          }
     
       //constructor method
          public Person(String fn, char mi, String ln, Date bDate, SSN soc) {
     
             firstName = fn;
             middleInitial = mi;
             lastName = ln;
             birthdate = bDate;
    	 social = soc;
          }
     
    	//toString Method
          public String toString() {
     
             String str = (	"\nFirst Name: " + firstName +
                			"\nMiddle Initial: " + middleInitial +
                			"\nLast Name: " + lastName +
    				"\nBirthdate: " + birthdate +
                			"\nSocial Security Number: " + social);
             return(str);
          }

    cannot find symbol
    symbol : constructor Person(java.lang.String, java.lang.String, java.lang.String, Date, java.lang.String)
    location: class Person
    Person Herman = new Person("Herman", 'H', "Wilson", sueBday, "111-11-1111");
    Does the Person class have a constructor that matches the one that you are calling in line 8?

    Where is sueBday? I don't see it in the code you posted.
