如何使用日誌記錄和追蹤來幫助調試Java函數？

import java.util.logging.Logger;

public class MyFunction {

    private static final Logger logger = Logger.getLogger(MyFunction.class.getName());

    public static void main(String[] args) {
        // 记录一条提示信息
        logger.info("函数开始执行");

        // 记录一条警告信息
        logger.warning("检测到潜在问题");

        // 记录一条错误信息
        logger.error("发生异常", new Exception("错误消息"));
    }
}

    }

    @Override

            traceServiceClient.createTraceRecord(TraceRecord.getDefaultInstance());
        }
    }
}
