Enums areused when we know all possible values at compile time, such as choices on a menu, rounding modes, command line flags, etc. It is not necessary that the set of constants in an enum type stay fixed for al
A HashMap in Java is a robust data structure that efficiently stores and retrieves key-value pairs. Falling under the ‘Map’ interface in the Java Collections Framework, HashMap offers a dynamic and flexible means of organizing data. The HashMap works on the principle of hashing, which inv...

添加了EnumCodec和EnumCodecProvider类,以便将enum类型的编解码器支持与PojoCodec类分开。 可通过MongoClientSettings和Bson接口访问的默认编解码器注册表现在包含enum编解码器类。 如果应用程序使用自定义枚举编解码器和默认注册表之一,请确保按照重写编解码器部分中的描述对它们进行排序。
Constants are basically variables whose value can't change. In C/C++, the keyword const is used to declare these constant variables. In Java, you use the keyword
NewExpression is compared to itselfinspection for Java A new inspection reports cases where an expression is being compared to itself instead of another.
