Learning Path: Serialization and Deserialization

POJO:

public class Employee implements Serializable{

private int empId;

private String empName;

transient private double salary;

//setter and getter methods

}

Serialization:

Employee employee;

employee=new Employee();

employee.setEmpId(1);

employee.setEmpName("name");

employee.setSalary(65000.00);

File file=null;

FileOutputStream fileoutputStream=null;

ObjectOutputStream objectOutputStream=null;

file=new File("emp2.txt");

fileoutputStream=new FileOutputStream(file);

objectOutputStream=new ObjectOutputStream(fileoutputStream);

objectOutputStream.writeObject(employee);

System.out.println("inserted.");

DeSerialization:

File file=null;

FileInputStream fileInputStream=null;

ObjectInputStream objectInputStream=null;

file=new File("emp2.txt");

fileInputStream=new FileInputStream(file);

objectInputStream=new ObjectInputStream(fileInputStream);

Object object=objectInputStream.readObject();

Employee e=(Employee) object;

System.out.println(e.getEmpId()+"\t"+e.getEmpName()+"\t"+e.getSalary());
