android - Update statement in Realm -

i have visitingcardpojo form table. want update single entry no=3

visitingcardpojo.java

public class visitingcardpojo extends realmobject {     @primarykey private int no;     private string name;     private string address;      public int getno() {         return no;     }      public void setno(int no) {         this.no = no;     }      public string getname() {         return name;     }      public void setname(string name) {         this.name = name;     }      public string getaddress() {         return address;     }      public void setaddress(string address) {         this.address = address;     } } 

i found solution , worked

 public void updatenewcard(realm realm, visitingcardpojo card) {         realm.begintransaction();         visitingcardpojo toedit = realm.where(visitingcardpojo.class)                 .equalto("no", card.getno()).findfirst();         toedit.setname(card.getname());         toedit.setaddress(card.getaddress());         realm.committransaction();     } 

see demo realm
