5.2 Creating a Java Bean Interface for a JDBC Connection

The JdbcBean.java class fetches a list of Employee objects.

Class Name: src/main/java/com/oracle/jdbc/samples/bean/JdbcBean.java

Github Location: JdbcBean.java

Steps to create JdbcBean.java:

1. Declare the package for the class JdbcBean.java.

   package com.oracle.jdbc.samples.bean;

2. Import Employee entity class as it contains the employee details.

   import com.oracle.jdbc.samples.entity.Employee;

3. Declare an interface EmployeeBean class. Inside the EmployeeBean class, declare a method getEmployees() that returns a list of Employee objects. Similarly, you learn to declare the methods getEmployee(int), updateEmployee(int), getEmployeeByFn(String) and incrementSalary(int) for other functionalities in the next few chapters.

   
   public interface EmployeeBean {
       public List<Employee> getEmployees(); 
   }
