public class searchExpress { public static void searchExpressinget(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"); } else { // 处理未找到快递的情况 } } catch (IOException e) { e.printStackTrace(); } } 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(); } } } 如何修改代码，使得其在快递点中找到快递，就不执行searchexpressinsend

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。
