java - How to pass an object from one activity to another on Android -

i trying work on sending object of customer class 1 activity , display in activity.

the code customer class:

public class customer {      private string firstname, lastname, address;     int age;      public customer(string fname, string lname, int age, string address) {          firstname = fname;         lastname = lname;         age = age;         address = address;     }      public string printvalues() {          string data = null;          data = "first name :" + firstname + " last name :" + lastname         + " age : " + age + " address : " + address;          return data;     } } 

i want send object 1 activity , display data on other activity.

how can achieve that?

one option letting custom class implement serializable interface , can pass object instances in intent using putextra(serializable..) variant of intent#putextra() method.

pseudocode:

//to pass: intent.putextra("myclass", obj);  // retrieve object in second activity getintent().getserializableextra("myclass");
