当我将另一个 JPanel 添加到前一帧中时,将会消失(或者可能与前一个重叠)。我怎样才能停止这种重叠?
public Attack() {
JFrame frame = new JFrame("Oracle Padding Attack");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
panel1.setLayout(null);
JLabel label1 = new JLabel("Inicialization vector:");
createTextField(10, 40, arrayIV, panel1, "HH", true, false);
label1.setBounds(10, 0, 120, 50);
panel1.add(label1);
panel2.setLayout(null);
JLabel label2 = new JLabel("Encrypted text:");
createTextField(400, 40, encryptedTextArray, panel2, "00", true, false);
label2.setBounds(400, 0, 120, 50);
panel2.add(label2);
frame.add(panel1);
frame.add(panel2);
frame.setSize(900, 400);
frame.setVisible(true);
}
