JAVA   

 public String toString() {
    return "Land Type:  " + landType + "\n" +
         "Address:  " + address + "\n" +
         "City:  " + city + "\n" +
         "State:  " + state + "\n";
  }
 
  public boolean equals (Property obj) {
    if (landType == obj.get_landType() && address == obj.address &&
        city == obj.get_city() && state == obj.get_state())
      return true;
    else
      return false;
  }
  
  public Property copy () {
    Property copyOfObject = new Property(landType, address, city, state);
    return (copyOfObject);
  }
  
  
}

Examine the method equals.

                  a.              What, if anything, does the method accept as input (parameter)?

                  b.              What, if anything, does the method return?

                  c.              How does the method determine if two objects are the same?
