I run another jFrame’s method, but doesn’t it add to the list?

Question

Good morning !

I need to know how to fill a table with data from another jFrame. I created a function in the Viewpedido class that fills the table, but when I run it through another frame, it doesn’t work. Maybe it’s the "new" that I pass when I urge, there’s a way I can do it without the "new"?

This function I run in jFrame Addpizza if I add a "request.setVisible(true)" it works, but creates another frame

    public void adicionarPizza() {
    DefaultTableModel modelo = (DefaultTableModel) tb_pizza.getModel();
    int linha = tb_pizza.getSelectedRow();
    
    Object[] pizza = {
        combo_qtd.getSelectedItem(),  
        modelo.getValueAt(linha, 1), 
        modelo.getValueAt(linha, 2)
    };
    
    ViewPedido pedido = new ViewPedido();
    pedido.addTeste(pizza);
}

This or function is in jFrame Viewpedido

    public void addTeste(Object[] pizza) {
    DefaultTableModel modelo = (DefaultTableModel) tb_pedido.getModel();
    modelo.addRow(pizza);
}

That’s what I need to do.
