I have a matrix in a jFrame in which I capture the data, when I click on a button of that frame, I have to open a second window where I show the matrix captured inside a table, the problem is that I do not know how To do it, I tried the method of using variables in both frames but it does not work. Thanks in advance.
public static class Form1 extends JFrame {
private JButton btn;
public Formulario1() {
super("Llamada");
btn = new JButton("Llamar");
setLayout(new BorderLayout());
add(btn, BorderLayout.CENTER);
setSize(100, 100);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
btn.addActionListener((ActionEvent ae) -> {
final Formulario2 frm = new Formulario2(new Object[]{"Dato1", "Dato2", "Dato3", 15});
frm.setVisible(true);
});
setVisible(true);
}
}
public static class Formulario2 extends JFrame {
private Object[] arr;
private JList lst;
private DefaultListModel mdl;
public Formulario2(Object[] arr) {
super();
this.arr = arr;
lst = new JList();
mdl = new DefaultListModel();
lst.setModel(mdl);
add(lst);
mostrarDatos();
}
public void mostrarDatos() {
if (arr != null && arr.length > 0) {
for (int i = 0; i < arr.length; i++) {
mdl.addElement(arr[i].toString());
}
}
}
}
}
