Explanation / Answer

Program Address.java

=======================================================
public class Address {

//Declare all required variables
private String street;
private String city;

//Default constructor
public Address() {

}

//Parameterized constructor
public Address(String street, String city) {
  this.street = street;
  this.city = city;
}

//All getters and setters method

public String getStreet() {
return street;
}

public void setStreet(String street) {
this.street = street;
}

public String getCity() {
return city;
}

public void setCity(String city) {
this.city = city;
}

@Override
public String toString() {
return "Street : "+street +" City : "+city;
}

}

Program Employee.java

=======================================================

public class Employee {

//Declare all required variables
private String dob;
private String ssn;
private Address address;

//Parameterized constructor
public Employee(String dob, String ssn, Address address) {
  this.dob = dob;
  this.ssn = ssn;
  this.address = address;
}

//equals method to compare two employee objects
public boolean equals(Object object) {

//Type cast to employee object
  Employee employeeOhter = (Employee)object;

//If dob and ssn of two employees are same return true
  if(this.dob==employeeOhter.dob && this.ssn==employeeOhter.ssn) {
  return true;
} else {
  return false;
}
  
}

}

Program EmployeeTest.java

=======================================================

public class EmployeeTest {

public static void main(String[] args) {

  //Create two employee objects
  Employee emp1 = new Employee("15/10/1991", "5872-4209-2347", new Address("Houstan", "Texas"));

  Employee emp2 = new Employee("15/10/1991", "5872-4209-2347", new Address("Houstan", "Texas"));

  //Check for equality
  if(emp1.equals(emp2)) {
   System.out.println("Two employees are identical");
  } else {
   System.out.println("Two employees are not identical");
  }
}

}
