如何从蓝牙套接字捕获错误并打印自定义消息？

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.bluetooth.BluetoothStateException;
import javax.bluetooth.RemoteDevice;
import javax.microedition.io.Connector;
import javax.microedition.io.StreamConnection;

public class BluetoothSocketExample {
    public static void main(String[] args) {
        try {
            // 建立蓝牙套接字连接
            String url = "btspp://001122334455:1;authenticate=false;encrypt=false;master=false";
            StreamConnection connection = (StreamConnection) Connector.open(url);

            // 获取输入输出流
            InputStream inputStream = connection.openInputStream();
            OutputStream outputStream = connection.openOutputStream();

            // 执行蓝牙通信操作
            // ...

            // 关闭连接
            inputStream.close();
            outputStream.close();
            connection.close();
        } catch (IOException e) {
            // 捕获IO异常并打印自定义错误消息
            System.out.println("蓝牙通信发生错误：" + e.getMessage());
        } catch (BluetoothStateException e) {
            // 捕获蓝牙状态异常并打印自定义错误消息
            System.out.println("蓝牙状态异常：" + e.getMessage());
        }
    }
}
