My task is to click on the button "add" in 1_activity, which sends me to 2_activity where i need to key my data into fields and click on the button "save", which saves the data and sends me back to the 1_activity, where i click on another button "see" and it sends me to 2_acitivty with filled data

1_activity

`public class MainActivity extends AppCompatActivity { ActivityMainBinding binding; public static final int CODE = 0; public static final String USER = "USER"; Intent i; public Form user; public String name;
