swing - Java - Custom JTabel show weird text -
i making application show data. won't. show weird string, said jeremy.itemsdata@33f1ca93 , table cell show jeremy.itemsdata@427a9389. here code. got code somewhere , modify because dont want application that.

thanks
here solution
@override public object getvalueat(int arg0, int arg1) { return (item == null) ? null : item.get(arg0).name; } it should
item.get(arg0).name; instead of
item.get(arg0); // returns object itemsdata class. you can in way overriding tostring() method of itemsdata class in existing code item.get(arg0);
class itemsdata{ public itemsdata(string string) { name = string; } public string name; @override public string tostring(){ return name; } }
