当选中多个复选框时如何执行操作？

Question

[当用户选中多个复选框时，我需要使用相同的名称执行以下操作。如何为此使用for循环条件？

如果只有一个选择被执行，我试图使用if-else。有什么方法可以实现for循环以减少代码长度？

我正在使用JFrame绝对布局，因此复选框变量已经预先定义。我无法使用数组。

public first() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 512, 263);
    contentPane = new JPanel();
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    setContentPane(contentPane);
    contentPane.setLayout(null);

    JLabel lblNewLabel = new JLabel("Checkout Suite:");
    lblNewLabel.setBounds(10, 11, 104, 20);
    contentPane.add(lblNewLabel);

    JComboBox comboBox = new JComboBox();
    comboBox.addItem("SNS Legacy checkout - Full Run - Desktop");
    comboBox.addItem("SNS Legacy checkout - Sanity Run - Mobile");
    comboBox.setBounds(124, 11, 331, 20);
    contentPane.add(comboBox);

如果使用else if，则一旦if返回true，它将停止执行更多的案例。一种可能会减少代码的方法是将所有复选框添加到ArrayList，然后循环遍历。

    List<JCheckBox> cbList = new ArrayList<>();

    JCheckBox chckbxNewCheckBox = new JCheckBox("US");
    chckbxNewCheckBox.setBounds(17, 94, 63, 23);
    contentPane.add(chckbxNewCheckBox);
    cbList.add(chckbxNewCheckBox);

    JCheckBox chckbxNewCheckBox_1 = new JCheckBox("UK");
    chckbxNewCheckBox_1.setBounds(104, 94, 63, 23);
    contentPane.add(chckbxNewCheckBox_1);
    cbList.add(chckbxNewCheckBox_1);

    JCheckBox chckbxNewCheckBox_2 = new JCheckBox("IN");
    chckbxNewCheckBox_2.setBounds(177, 94, 72, 23);
    contentPane.add(chckbxNewCheckBox_2);
    cbList.add(chckbxNewCheckBox_2);

    JCheckBox chckbxNewCheckBox_3 = new JCheckBox("JP");
    chckbxNewCheckBox_3.setBounds(17, 133, 63, 23);
    contentPane.add(chckbxNewCheckBox_3);
    cbList.add(chckbxNewCheckBox_3);

    JCheckBox chckbxNewCheckBox_4 = new JCheckBox("FR");
    chckbxNewCheckBox_4.setBounds(104, 133, 63, 23);
    contentPane.add(chckbxNewCheckBox_4);
    cbList.add(chckbxNewCheckBox_4);

    JCheckBox chckbxNewCheckBox_5 = new JCheckBox("DE");
    chckbxNewCheckBox_5.setBounds(177, 133, 72, 23);
    contentPane.add(chckbxNewCheckBox_5);
    cbList.add(chckbxNewCheckBox_5);

    JCheckBox chckbxNewCheckBox_6 = new JCheckBox("ES");
    chckbxNewCheckBox_6.setBounds(17, 174, 63, 23);
    contentPane.add(chckbxNewCheckBox_6);
    cbList.add(chckbxNewCheckBox_6);

    JCheckBox chckbxNewCheckBox_7 = new JCheckBox("IT");
    chckbxNewCheckBox_7.setBounds(104, 174, 63, 23);
    contentPane.add(chckbxNewCheckBox_7);
    cbList.add(chckbxNewCheckBox_7);

    JCheckBox chckbxNewCheckBox_8 = new JCheckBox("CA");
    chckbxNewCheckBox_8.setBounds(177, 174, 72, 23);
    contentPane.add(chckbxNewCheckBox_8);
    cbList.add(chckbxNewCheckBox_8);

[Alexeys的评论让我考虑是否要检查任何复选框，这可能在一开始就很有用。

private boolean selectionWasMade()
{
    int selectedCounter = 0;

    for(JCheckBox checkbox : cbList)
    {
        if(checkbox.isSelected())
        {
            selectedCounter++;
        }
    }

    if(selectedCounter != 0)
    {
        return true;
    }
    return false;
}

现在您只需检查它是否返回true并执行此循环：

if(selectionWasMade())
{
    for(JCheckBox checkbox : cbList)
    {
        if(checkbox.isSelected())
        {
            aru.findElement(By.id("name")).sendKeys("SNS - Checkout Preflight - Desktop - " + checkbox.getText() + " - "+content);
        }
    }
}
else
{
    JOptionPane.showMessageDialog(null, "Please select from list");
}
