[Java]{Lama dotaz}Nacitani matice v GUI

[viki_]

Zkus tohle - je to naklikane behem 5ti minut, takze si s tim muzes vyhrat lepe. Hodnoty se zadavaji do JTable, po stisku tlacitka se obsah matice vypise na konzoli. Rozmery matice jsou v konstantach na zacatku. Pokud je tam chybny vstup, doplni se nula.
