如何在java中刷新蓝牙设备列表？

import javax.bluetooth.*;
import java.io.IOException;

public class BluetoothDeviceDiscovery {

    public static void main(String[] args) {
        try {
            // 创建一个本地蓝牙适配器
            LocalDevice localDevice = LocalDevice.getLocalDevice();

            // 开启设备的可发现性
            boolean discoverable = localDevice.setDiscoverable(DiscoveryAgent.GIAC);

            // 创建一个对象用于发现蓝牙设备
            DiscoveryAgent agent = localDevice.getDiscoveryAgent();

            // 创建一个监听器来处理发现的设备
            DiscoveryListener listener = new DiscoveryListener() {
                @Override
                public void deviceDiscovered(RemoteDevice remoteDevice, DeviceClass deviceClass) {
                    try {
                        // 获取设备名称和地址
                        String deviceName = remoteDevice.getFriendlyName(false);
                        String deviceAddress = remoteDevice.getBluetoothAddress();
                        System.out.println("发现设备：" + deviceName + " (" + deviceAddress + ")");
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void inquiryCompleted(int discType) {
                    System.out.println("设备搜索完成");
                }

                @Override
                public void serviceSearchCompleted(int transID, int respCode) {
                }

                @Override
                public void servicesDiscovered(int transID, ServiceRecord[] servRecord) {
                }
            };

            // 开始搜索蓝牙设备
            agent.startInquiry(DiscoveryAgent.GIAC, listener);

            // 等待搜索完成
            Thread.sleep(5000);

            // 停止搜索
            agent.cancelInquiry(listener);
        } catch (BluetoothStateException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
