output from the array list looks like address instead of data

Question

a simple android program which accept a user id and user name, and store them inside an arrayList using a subclass called Student. There are 2 buttons, one of them record the information and the other one display them. The top button seem to work fine, but for the other one it display something that looks like the address instead of the actual data, what's the problem? Thanks

Post your code here and you did not implement `toString` in your pojo. — Murat Karagöz, Sep 18 '18 at 12:38
you don't have getter for name. It should be `output.append(studetnList.get(i).getName())` — bakero98, Sep 18 '18 at 12:43

Override Object.toString() in your Student class.

//Sample code
public String toString() {
        return "id of the student:" + this.id + ",, "
                + "name of the student:" + this.name ;
    }

use this code for you funclist method

    private void funclist(){
        StringBuilder output = new StringBuilder();
        for(int i=0;i<studentList.seize();i++){
        output.append(studentList.get(i) + "\n");
        }
    }

this will convert your object to string or you can add

    studentList.get(i).toString()

instead of your code.
