JAXB 2.0 - Reading XML File in Java

In this post, We are going to read the XML file created in the previous post.We are using all other file from the previous post except Writer.java.

Below the code to read the sample XML file - department.xml.

department.xml

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Department>
    <Department Id>1</Department Id>
    <Department Name>HR</Department Name>
    <Employees>
        <Employee>
            <Employee Id>1</Employee Id>
            <Employee Name>Abhay</Employee Name>
            <Employee Age>12</Employee Age>
        </Employee>
        <Employee>
            <Employee Id>2</Employee Id>
            <Employee Name>Pawan</Employee Name>
            <Employee Age>32</Employee Age>
        </Employee>
        <Employee>
            <Employee Id>3</Employee Id>
            <Employee Name>Jai</Employee Name>
            <Employee Age>18</Employee Age>
        </Employee>
        <Employee>
            <Employee Id>4</Employee Id>
            <Employee Name>Rajan</Employee Name>
            <Employee Age>21</Employee Age>
        </Employee>
    </Employees>
</Department>

Reader.java

package com.javainstance;

import java.io.File;
import java.util.List;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;

/**

public class Reader {

public static void main(String[] args) {

try {

File xmlFile = new File("department.xml");
JAXBContext context = JAXBContext.newInstance(Department.class);

Unmarshaller unmarshaller = context.createUnmarshaller();
Department dept = (Department) unmarshaller.unmarshal(xmlFile);

System.out.println(
"Department Id:" + dept.getDepartmentId() + " " + "Department Name:" + dept.getDepartmentName());
System.out.println();
System.out.println("Employees Details in Department:" + dept.getDepartmentName());
System.out.println();
List<Employee> employeeList = dept.getEmployees();
employeeList.forEach((Employee) -> {
System.out.println("Employee Id: " + Employee.getEmployeeId() + " " + "Employee Name: "
+ Employee.getEmployeeName() + " " + "Employee Age: " + Employee.getEmployeedAge());
}

);
} catch (JAXBException e) {
e.printStackTrace();
}

}

}

Output:

Department Id:1 Department Name:HR

Employees Details in Department:HR

Employee Id: 1 Employee Name: Abhay Employee Age: 12

Employee Id: 2 Employee Name: Pawan Employee Age: 32

Employee Id: 3 Employee Name: Jai Employee Age: 18

Employee Id: 4 Employee Name: Rajan Employee Age: 21
