Easy learning with example program codes

store and read objects from a file java program


package com.codesjava;
public class Employee implements Serializable {
    private static final long serialVersionUID = 1L;
    private String empName;
    private int empId;
    private String salary;
    public Employee(String empName, int empId, String salary){
        this.empName = empName;
        this.empId = empId;
        this.salary = salary;
    public String toString(){
        return "Emp Name: "+empName +", Emp Id: "
        		+empId+", Salary: "+salary;
	public String getEmpName() {
		return empName;
	public void setEmpName(String empName) {
		this.empName = empName;
	public int getEmpId() {
		return empId;
	public void setEmpId(int empId) {
		this.empId = empId;
	public String getSalary() {
		return salary;
	public void setSalary(String salary) {
		this.salary = salary;

package com.tutorialspointexamples;
public class ObjectFileProcessing {
	public void storeObject(Employee emp){
        OutputStream ops = null;
        ObjectOutputStream objOps = null;
        try {
            ops = new FileOutputStream("EmpFile.txt");
            objOps = new ObjectOutputStream(ops);
        } catch (Exception e) {
    public void displayObjects(){         
        InputStream fileIs = null;
        ObjectInputStream objIs = null;
        try {
            fileIs = new FileInputStream("EmpFile.txt");
            objIs = new ObjectInputStream(fileIs);
            Employee emp = (Employee) objIs.readObject();
        } catch (Exception e) {

package com.tutorialspointexamples;
public class FileObjectTest {
  public static void main(String args[]){
      ObjectFileProcessing objectFileProcessing = new ObjectFileProcessing();
      Employee e1 = new Employee("Vikas",5,"50000");


Emp Name: Vikas, Emp Id: 5, Salary: 50000
