indexoutofboundsexception - Java- adding a new row to a JTable in GUI -



indexoutofboundsexception - Java- adding a new row to a JTable in GUI -

i have simple java gui displaying empty table , few buttons. trying add together listener 1 of buttons add together new empty row (with editable cells) table in gui.

i using next code seek , this:

jbutton addbtn = new jbutton("add"); addbtn.addactionlistener(new actionlistener(){ public void actionperformed(actionevent e){ system.out.println("'add' button pressed. "); defaulttablemodel model = (defaulttablemodel)jentityfiltertable.getmodel(); model.addrow(new object[]{"site", "application", "entity"}); system.out.println("--- actionlistener added 'addbtn' ---"); } });

however, when click button, getting java.lang.arrayindexoutofboundsexception. says occurring on next line:

model.addrow(new object[]{"site", "application", "entity"});

i not sure why i'm getting exception... i've created new object[] array, , given 3 elements... i'm not trying access elements (or elements don't exist)...

can point out i'm doing wrong here?

i think work

defaulttablemodel model = (defaulttablemodel) jentityfiltertable.getmodel(); vector row = new vector(); row.add("site"); row.add("application"); row.add("entity"); model.addrow(row);
