在一个方法中，每次往不同properties中写入键值对时，都需要重新new一个对象吗

Question

            out=new FileOutputStream("src/main/resources/properties/grpc_service.properties");
            pps.store(out,"andieguo modify" + new Date().toString());
            out.close();
            out=new FileOutputStream("src/main/resources/properties/jdbc.properties");
            pps1.store(out,"andieguo modify" + new Date().toString());
            out.close();
            out=new FileOutputStream("src/main/resources/properties/Kafka_setting.properties");
            pps2.store(out,"andieguo modify" + new Date().toString());
            out.close();
各位大神有没有好一点的建议，，，

Answer 1

将new Properties的过程放到单例模式可以吗。

Answer 2

这个功能要考虑同一jvm中并发的，单例不能并发
