See the changes I have done in your code. May be this is what you are looking.

Code:

class Employee
{
    private Name Nam;
    private Address Addr;

    public Employee() {
        Addr = new Address("Street", "City", "State", "Zip");
        Nam = new Name("First", "Middle", "Last");
    }

    private String getName() {
       return Nam.toString();
    }

    private String getAddress() {
       return Addr.toString();
    }

    private String getSSN() {
       return "SSN";
    }
    
    private String printValues() {
        return "Name: " + getName() + "\n" +
                "Address: " + getAddress() + "\n" +
                "SSN: " + getSSN();
    }

    public static void main(String[] args) {
        System.out.println(new Employee().printValues());
    }

}

Code:

class Address
{
    private String strStreet;
    private String strCity;
    private String strState;
    private String strZip;

    public Address(String Street, String City, String State, String Zip){
       this.strStreet = Street;
       this.strCity = City;
       this.strState = State;
       this.strZip = Zip;
    }

    @Override
    public String toString()
    {
       return strStreet + " " + strCity + " " + strState + " " + strZip;
    }
}

Code:

class Name
{
    private String strFirst;
    private String strMiddle;
    private String strLast;

    public Name(String FName, String MName, String LName) {
       strFirst = FName;
       strMiddle = MName;
       strLast = LName;
    }

    @Override
    public String toString() {
       return strFirst + " " + strMiddle + " " + strLast;
    }
}
