ajax - JTable with annotation in Java -

how can create jtable in java using annotation? this: jtable table=new jtable(products.class). can i? products class several attributes like:id,price,productname.

there article , source code in codeproject this: http://www.codeproject.com/articles/36170/simple-and-powerfull-tablemodel-with-reflection

there no such annotations comes java runtime (at least now). can implement own method.

define annotation mark columns given object:

public @interface tablecolumn {     string name();     int index(); } 

mark fields want display in model object annotation:

class product {     @tablecolumn(name="product name", index=0)     string productname;     .... } 

create new tablemodel class -you can inherit defaulttablemodel- , check given annotation given object.

class objecttablemodel extends defaulttablemodel {     private object[] objects;     private string[] columns;     public objecttablemodel(object[] objects) {         field[] fields = object.class.getdeclaredfields();         (field field : fields) {             if (field.isannotationpresent(tablecolumn.class)) {                 //add field list             }         }     }      @override     public object getvalueat(int rowindex, int columnindex) {         //return value objects[rowindex]      }      @override     public int getrowcount() {         return objects.length;     }      @override     public int getcolumncount() {         return columns.length;     }      @override     public string getcolumnname(int column) {         return columns[column];     }      @override     public class<?> getcolumnclass(int columnindex) {         return columnclasses[columnindex];     } }
