Question

Create a new project for Constructor Injection. Create three classes, Address.java, Employee.java and Department.java with the following fields :

Address.java

1) int houseNumber

2) String streetName

3) String zipCode

Department.java

int departmentId

String departmentName

Employee.java

1) String firstName

2) String lastName

3) String ssn;

4) Address address

5) Department department

Using Spring Constructor Injection inject Address and Department into the Employee class.

Answer 1

_{java code}

import java.io.*;

class Address

{

int houseNumber;

String streetName;

String zipcode;

public String.toString()

{

return "streetname"+"zipcode";

}

public Integer.toString()

{ return "houseNumber";

}

}

class Department

{

String departmentName;

int departmentd;

public String.toString()

{

return "departmentName";

}

public Integer.toString()

{ return "departmentId";

}

}

class Employee

{

String firstname;

String ssn;

String lastname;

Address address=new Address();

Department department=new Department()

Employee(String t,int y,String f,String l,String m ,int a,string b,string c) //Constructor Injection

{

Address.streetName=b;

Address.zipcode=c;

Address.houseNumber=a

Department.departmentName=t;

Department.departmentId=y;

firstname=f;

ssn=m;

lastname=l;

}

}

void display()

{

System.out.println(address);

System.out.println(department);

System.out.println(firstname+""+lastname+""+ssn+""+Address.streetName+""+Address.zipcode+""+Address.houseNumber +""+Department.departmentName+""+Department.departmentId);

}

}class Emain

{

public static void main(String args[])

{Employee e=new Employee("computerSc",23,"Rahul","sharma","abc",56,"madis_street",3454);

e.display();

}

}
