How can I fill an object matrix

I have an object matrix, and I have to fill it with string. How can I do this? Let me explain well, I have declared a matrix of objects of fixed size, now I have to fill it through for loops, how can I access the cells of the matrix. I put the code of matrix down. Sorry but is in Italian. Giorno = day, ore = Hour

tabMedie = new JTable();
tabMedie.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
tabMedie.setFont(new Font("Times New Roman", Font.PLAIN, 10));
tabMedie.setModel(new DefaultTableModel(
    new Object[][] {
        {"Orari", "Giorno 1", "Giorno 2", "Giorno 3", "Giorno 4", "Giorno 5", "Giorno 6", "Giorno 7"},
        {"1", "", "", "", "", "", "", ""},
        {"2", "", "", "", "", "", "", ""},
        {"3", "", "", "", "", "", "", ""},
        {"4", "", "", "", "", "", "", ""},

    }

>Solution :

First, store the “matrix” (actually a two-dimensional array) in a variable:

String[][] texts = { { "Ora", "Giorno 1", … }, … };

And then, you can use it in a for loop:

for (int x = 1; x < 8; x++) {
    for (int y = 1; y < texts.length; y++) {
        texts[y][x] = "Your Text Here";
    }
}

And finally, you can pass it to the method as an argument:

new DefaultTableModel(texts, new String[] { … }) { … };
