    private String name;
    private java.util.Date dateCreated;
   
    public student(int ssn, String newName)
    {
        id = ssn;
        name = newName;
        dateCreated = newjava.util.Date();
    }
   
    public int getId()
    {
        return id;
    }
   
    public String getName()
    {
        return name;

}

Explanation / Answer

public class student
{
    private int id;
    private String name;
    private java.util.Date dateCreated;

    private Stringyear;

    private Stringmajor;
   
    public student(int ssn, String newName, Sringyear1, String major1)
    {
        id = ssn;
        name = newName;
        dateCreated = newjava.util.Date();

        this.year = year1;   // mutator

       this.major = major1;  //mutator
    }
   
    public int getId()
    {
        return id;
    }
   
    public String getName()
    {
        return name;
       
    }
   
    public java.util.Date getDateCreated()
    {
        return dateCreated;
       
    }
   public StringgetYear() //Accessor
    {
        return year;
    }
   
    public String getMajor() // Accessor
    {
        return major;
