Task: Overriding (Redesign the CanadianAddress class) This task will rewrite the CanadianAddress class you implemented in Lab 12 with overridden methods. The new class is also called CanadianAddress. If you do need the old CanadianAddress class, put this new class in a different package. Rewrite the CanadianAddress class: • From your implementation of the CanadianAddress class in Lab 12, delete the methods printAddress() and equalAddresses(). • You will replace the functionalities provided in the old printAddress() method with the following two steps: 1. In the CanadianAddress class, override the toString() method in the Object class, which returns a string in the format used by the old printAddress() method: streetAddress + "," + city + "\n" + province + " " + postalCode + ", Canada". Use the @Override annotation to make sure you override the toString() method correctly. 2. This toString() method will be implicitly used in the printing methods in your test program to print out an address. • You will replace the functionalities provided in the old equalAddresses() method in this step. Override the equals() method in the Object class. Note that the header of the method should be: public boolean equals(Object address), where the parameter is of Object type. Use the @Override annotation to make sure you override the equals() method correctly.

Question

Write the answer in java and read the question carefully here is the lab 12 code : 

public class lab12daneshelahi
{
  public static void main (String[]args)
  {
CanadianAddress testAddress = new CanadianAddress ();
CanadianAddress SMUAddress =
 new CanadianAddress ("923 Robie St.", "Halifax", "Nova Scotia",
  "B3H 3C3");
 
 System.out.println ("The testAddress is created as:");
 testAddress.printAddress ();
 System.out.println ();
 
 System.out.println ("The SMUAddress is created as:");
 SMUAddress.printAddress ();
 System.out.println ();
 
 System.out.println ("The testAddress is equal to SMUAddress? :( " +
 testAddress.equalAddress (SMUAddress));
 System.out.println ();
 
 testAddress.setStreetAddress ("923 Robie St.");
 testAddress.setCity ("Halifax");
 testAddress.setProvince ("Nova Scotia");
 testAddress.setPostalCode ("B3H 3C3");
 
 System.out.println ("The testAddress is updated as: :D ");
 testAddress.printAddress ();
 System.out.println ();
 
 System.out.println ("The testAddress is equal to SMUAddress? :) " +
 testAddress.equalAddress (SMUAddress));
  }
}
 
class CanadianAddress
{
  private String streetAddress;
  private String city;
  private String province;
  private String postalCode;
 
  public CanadianAddress ()
  {
  }
 
  public CanadianAddress (String streetAddress, String city, String province,
 String postalCode)
  {
this.streetAddress = streetAddress;
this.city = city;
this.province = province;
this.postalCode = postalCode;
  }
 
  public String getStreetAddress ()
  {
return streetAddress;
  }
 
  public void setStreetAddress (String streetAddress)
  {
this.streetAddress = streetAddress;
  }
 
  public String getCity ()
  {
return city;
  }
 
  public void setCity (String city)
  {
this.city = city;
  }
 
  public String getProvince ()
  {
return province;
  }
 
  public void setProvince (String province)
  {
this.province = province;
  }
 
  public String getPostalCode ()
  {
return postalCode;
  }
 
  public void setPostalCode (String postalCode)
  {
this.postalCode = postalCode;
  }
 
  public void printAddress ()
  {
System.out.println ((streetAddress != null ? streetAddress : "null") +
", " + (city != null ? city : "null") + ",");
System.out.println ((province != null ? province : "null") + " " +
(postalCode !=
null ? postalCode : "null") + ", Canada");
  }
 
  public boolean equalAddress (CanadianAddress address)
  {
return (this.streetAddress == null ? address.streetAddress ==
null : this.streetAddress.equals (address.streetAddress))
 && (this.city == null ? address.city ==
 null : this.city.equals (address.city))
 && (this.province == null ? address.province ==
 null : this.province.equals (address.province))
 && (this.postalCode == null ? address.postalCode ==
 null : this.postalCode.equals (address.postalCode));
  }
}

Please follow what in the question says and dont copy from other sources and dont plagarise please. Thank you.

Rewrite the TestCanadianAddress class to test the new CanadianAddress class: • From your implementation of the TestCanadianAddress class in Lab 12, instead of the printAddress() method, use the printing methods from System.out to perform all the outputs. (Hint: You can supply a reference variable to the printing methods. The toString() method will be implicitly invoked. For example, System.out.println(address) is the same as System.out.println(address.toString()).) • Instead of the equalAddresses() method, use the equals() method to test whether two addresses have identical content. Here is a sample run: (same as Lab 12) The testAddress is created as: null, null, null null, Canada The SMUAddress is created as: 923 Robie St., Halifax, Nova Scotia B3H 3C3, Canada The testAddress is equal to SMUAddress? false The testAddress is updated as: 923 Robie St., Halifax, Nova Scotia B3H 3C3, Canada The testAddress is equal to SMUAddress? true
