A 2-dimensional array of JButtons and setting text on them

gistfile1.java

// an array of JButtons
JButton[][] buttons = new JButton[4][4];

/* actually creates each of the sixteen JButton objects and sets
each button's text to look something like "Button [1][2]" (depending on row and column) */
for (int i=0; i < buttons.length; i++) {
    for (int j=0; j < buttons[i].length; j++) {
        buttons[i][j] = new JButton("Button [" + i + "][" + j + "]");
    }
}

// set the text later on some specific button if we want
buttons[2][3].setText("changed text");
