Creating a Java Bean Entity for an Employee
The Employee
class contains the getter and setter methods
for all attributes of an employee. For example, the First_name
has a getter and
a setter method like getFirst_Name
and setFirst_Name
respectively.
Class Name:
src/main/java/com/oracle/jdbc/samples/entity/Employee.java
Github Location: Employee.java
Steps to create Employee.java:
- Declare the package for the class
Employee.java
.package com.oracle.jdbc.samples.entity;
- Import the following packages required for the
Employee
class.import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Timestamp;
- Declare an
Employee
class. Add a pair of parenthesis ({ }). Place the cursor in between the parenthesis:public class Employee {}
- Declare the following variables for each one of the attributes of an
employee.
private int Employee_Id; private String First_Name; private String Last_Name; private String Email; private String Phone_Number; private String Job_Id; private int Salary;
- Create a constructor for the
Employee
class which takes ResultSet as the input and throws a SQLException. In this constructor, set all the values for the attributes of theEmployee
class.public Employee(ResultSet resultSet) throws SQLException { this.Employee_Id = resultSet.getInt(1); this.First_Name = resultSet.getString(2); this.Last_Name = resultSet.getString(3); this.Email = resultSet.getString(4); this.Phone_Number = resultSet.getString(5); this.Job_Id = resultSet.getString(6); this.Salary = resultSet.getInt(7); }
- Create the Getter and Setter methods, that is, getX and setX methods to get
and set the values for all attributes of the
Employee
such asEmployee_id
,first_name
,last_name
,salary
, and so on. For example, the getter and setter methods for theEmployee_Id
is as follows:public int getEmployee_Id() { return Employee_Id; } public void setEmployee_Id(int Employee_Id) { this.Employee_Id = Employee_Id; }
