swing - JComboBox - Unable to get the value -


i've created jcombobox in table per below.

code

          tablecolumn col5 = jtable1.getcolumnmodel().getcolumn(4);                 string[] options = new string[]{"font issue","text issue","image issue","ai issue","others"};           jcombobox combo1 = new jcombobox(options);           jcombobox combo2 = new jcombobox(options);           col5.setcelleditor(new defaultcelleditor(combo1));           col5.setcellrenderer(new comboboxrenderer(combo2));           col5.setpreferredwidth(150);           combo2.addactionlistener(new actionlistener() {             public void actionperformed(actionevent e) {                                 string dropdownvalue = col5.getcelleditor().getcelleditorvalue().tostring();                 if(dropdownvalue.equalsignorecase("others"))                 {                     joptionpane.showmessagedialog(null, "alert", "alert", "");                 }             }         });

there error when try dropwon value.

error

local variable col5 accessed within inner class; needs declared final.

i tried this. 

string dropdownvalue = combo1.getselecteditem().tostring();

but similiar error 

local variable combo1 accessed within inner class; needs declared final

please help. thanks

change 

 tablecolumn col5 = jtable1.getcolumnmodel().getcolumn(4);

to

 final tablecolumn col5 = jtable1.getcolumnmodel().getcolumn(4);

you defining anonymous class. avoid strange side-effects closures in java variables must marked final.
