                StudentHome studentHome = new StudentHome();
                frame.dispose();
                studentHome.setVisible(true);
            }
        });

        btnNewButton.setBounds(27, 11, 52, 48);
        contentPane.add(btnNewButton);

        JLabel lblHome = new JLabel("Home");
        lblHome.setForeground(new Color(0, 0, 153));
        lblHome.setBounds(37, 70, 46, 14);
        contentPane.add(lblHome);
    }
}

使用Windows类有一个名为dispose的方法。

JFrame,继承自Frame,而Frame继承自Windows。您的类继承自JFrame,因此您可以直接访问dispose()方法。

英文:

Use Windows class has a method dispose.

JFrame, extends Frame, which in turn extends Windows. Your class extends JFrame, thus you have a direct access to dispose().
