Question

我有一些重复的代码，我希望将其付诸实践。但问题是我使用全局变量，我无法发送功能，任何想法如何缩短我的代码？

public class MainClass extends JFrame {

private static List<JComboBox> sundayCombo;
private static List<JComboBox> mondayCombo;
private static List<JComboBox> tuesdayCombo;
private static List<JComboBox> wednesdayCombo;
private static List<JComboBox> thursdayCombo;
private static List<JComboBox> fridayCombo;
private static List<JComboBox> saturdayCombo;

public static void main(String[] args) {

sundayCombo = new ArrayList<>();
    mondayCombo = new ArrayList<>();
    tuesdayCombo = new ArrayList<>();
    wednesdayCombo = new ArrayList<>();
    thursdayCombo = new ArrayList<>();
    fridayCombo = new ArrayList<>();
    saturdayCombo = new ArrayList<>();

    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                MainClass frame = new MainClass();
                frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });


}

public MainClass() {

for (String string : mylist) {

        //Create function for the next section
        //Some thing like this:
        //createPanel(sundayCombo,panel_sunday_therapist);

        JComboBox comboBox1 = createComboBox();
        sundayCombo.add(comboBox1);
        panel_sunday_nurse.add(comboBox1);
        panel_sunday_nurse.add(Box.createVerticalStrut(STRUT_SIZE));

        JComboBox comboBox2 = createComboBox();
        mondayCombo.add(comboBox2);
        panel_monday_nurse.add(comboBox2);
        panel_monday_nurse.add(Box.createVerticalStrut(STRUT_SIZE));

        JComboBox comboBox3 = createComboBox();
        tuesdayCombo.add(comboBox3);
        panel_tuesday_nurse.add(comboBox3);
        panel_tuesday_nurse.add(Box.createVerticalStrut(STRUT_SIZE));

        JComboBox comboBox4 = createComboBox();
        wednesdayCombo.add(comboBox4);
        panel_wednesday_nurse.add(comboBox4);
        panel_wednesday_nurse.add(Box.createVerticalStrut(STRUT_SIZE));

        JComboBox comboBox5 = createComboBox();
        thursdayCombo.add(comboBox5);
        panel_thursday_nurse.add(comboBox5);
        panel_thursday_nurse.add(Box.createVerticalStrut(STRUT_SIZE));

        JComboBox comboBox6 = createComboBox();
        fridayCombo.add(comboBox6);
        panel_friday_nurse.add(comboBox6);
        panel_friday_nurse.add(Box.createVerticalStrut(STRUT_SIZE));

        JComboBox comboBox7 = createComboBox();
        saturdayCombo.add(comboBox7);
        panel_saturday_nurse.add(comboBox7);
        panel_saturday_nurse.add(Box.createVerticalStrut(STRUT_SIZE));


    }

    }

private JComboBox createComboBox() {

    //bla bla
    return comboBox;
}

}

您可以创建一个函数，将您希望添加的组合框作为函数的参数，即

using System;
using System.Net.Http;
using System.Threading.Tasks;

namespace TestApi
{
    public class MyController : Controller
    {
        private const string ApiUrlString = "https://apiUrl.com";
        private static readonly Uri ApiUri = new Uri(ApiUrlString);
        private static readonly HttpClient RestClient;

        static MyController()
        {
            this.RestClient = new HttpClient{
                BaseAddress = ApiUri
            }
            this.RestClient.DefaultRequestHeaders.Accept.Clear();
            this.RestClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            RestClient.DefaultRequestHeaders.TryAddWithoutValidation("APIAccessToken", "token1");
            RestClient.DefaultRequestHeaders.TryAddWithoutValidation("UserToken", "token2");
        }

        public async Task<IActionResult> ApiTest()
        {
            return this.Ok(await this.RestClient.GetStringAsync("somedata/search?text=test"));
        }
    }
}

您可以将该功能称为private void addComboBox(List<JComboBox> weekdayCombo, JPanel weekdayPanel) { ComboBox comboBox1 = createComboBox(); weekdayCombo.add(comboBox1); weekdayPanel.add(comboBox1); weekdayPanel.add(Box.createVerticalStrut(STRUT_SIZE)); }
