Passing object between activity by using Serializable

Here we passing Serializable object and List of Object From one activity to another activity.
if you want to pass custom object from one activity to another activity you need to implement Serializable interface.
This is student class having some property in that case I want to transfer student object and list of student object between Activity. if you want to know about Serialization you can refer this link.

public class Student implements Serializable {

    private String name;
    private int age;
    private String  address;
    private String city;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {

    public void setAge(int age) {
        this.age = age;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
