data = in.readLine(); //*********Found********** x = Integer.parseInt(data);

这行Java代码的作用是在读取输入流（通常是一个文本文件或控制台输入）时，从`in`这个输入流中获取一行数据，并将其作为字符串存储在`data`变量中。`readLine()`函数会读取到下一行文本，直到遇到换行符为止。

然后，通过`Integer.parseInt(data)`将字符串`data`转换成整数类型，并将结果赋值给变量`x`。`parseInt()`函数用于解析字符串并返回对应的整数值，如果字符串不能有效转换为整数，则会抛出`NumberFormatException`异常。

要实现在找到快递时不执行`searchExpressInSend`方法，你可以在`searchExpressGet`方法中添加一个条件判断。如果找到快递，就直接返回，而不执行后续的代码。修改后的代码如下：

public class SearchExpress {
    public static void searchExpressGet(String trackingNumber) {
        boolean found = false;
        try (BufferedReader in = new BufferedReader(new FileReader("C:/eclipse-workspace/dragon/getexpress.txt"))) {
            String line;
            while ((line = in.readLine()) != null) {
                String[] data = line.split(",");
                if (data[0].equals(trackingNumber)) {
                    found = true;
                    break;
                }
            }
            if (found) {
                JOptionPane.showMessageDialog(null, "快递已在快递点");
                return; // 找到快递时直接返回
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        
        // 如果未找到快递，则执行searchExpressInSend方法
        searchExpressInSend(trackingNumber);
    }

    public static void searchExpressInSend(String trackingNumber) {
        boolean found = false;
        try (BufferedReader in = new BufferedReader(new FileReader("C:/eclipse-workspace/dragon/sendexpress.txt"))) {
            String line;
            while ((line = in.readLine()) != null) {
                String[] data = line.split(",");
                if (data[0].equals(trackingNumber)) {
                    found = true;
                    break;
                }
            }
            if (found) {
                JOptionPane.showMessageDialog(null, "快递已发出");
            } else {
                JOptionPane.showMessageDialog(null, "快递未找到，请联系相应客服处理");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

在`searchExpressGet`方法中，当找到快递时，使用`return`语句直接返回，不再执行后续的代码。这样就可以实现在快递点中找到快递时不执行`searchExpressInSend`方法。

using System.Net.Http; using System.Net.Http.Headers; using System.Web; using Newtonsoft.Json; using System.Net; private static void GetCardInformation(string token) { using (var httpClientGet = new HttpClient()) { httpClientGet.BaseAddress = new Uri("https://cdu-test.arcelik.com/CardDataApi/"); httpClientGet.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token); var barcode = "TT0167260099161800197700000000001601010403000205020011e147db530000000000"; var responseGet = httpClientGet.GetAsync("api/CardData/GetProductCardData?barcode="+ barcode).Result.Content.ReadAsStringAsync().Result; ReturnModel<CardDataModel> resultObj = JsonConvert.DeserializeObject<ReturnModel<CardDataModel>>(responseGet); if (resultObj.Status == ReturnTypeStatus.Success) { Console.WriteLine("Card found in cloud"); //"Data" attr in "resultObj" provides card informations in your query above. } else if (resultObj.Status == ReturnTypeStatus.NotFound) { //result not found message Console.WriteLine(resultObj.Message); } else if (resultObj.Status == ReturnTypeStatus.Error) { //error message Console.WriteLine(resultObj.Message); } Console.ReadLine(); } }

这段代码是用来获取指定条形码（barcode）商品的信息。它使用了 HttpClient 类库来发送 GET 请求，其中包含访问令牌（access token）和指定的条形码信息。在服务器端验证通过后，会返回一个包含商品信息的 JSON 数据，这里使用了 NewtonSoft.Json 类库来解析 JSON 数据。最后，根据返回的状态码，判断查询结果，并将结果输出到控制台。
