Question

How to pass value from one class to jcombobox in another class

Public void getItem (){
try {
         dBconnection...
              while(rs.next){
                  String customers = rs.getString (1);
this.jcombobox1.addItem (customers);
}

}

}

From this method to jcombobox in another class. The error is in jcombobox?

Answer 1

Since you are already having B's class object in A lets say ex Bclassobj.

Public void getItem (){
try {
       while(rs.next){
         this.jcombobox1.addItem (rs.getString (1));
         Bclassobj.Bclassjcombobox.addItem (rs.getString (1));
     }

    }
   }
