泛型相当有用，因为他们提供强制的编译时类型检查，要求更少的数据类型之间的显式转换，并减少装箱拆箱的操作和运行时类型检查。

Generics are useful because they provide stronger compile-time type checking, require fewer explicit conversions between data types, and reduce the need for boxing operations and run-time type checks.

当把一个“数据”从值类型转换成引用类型的时候，就叫做“装箱”，反之叫做“拆箱”。

When the data moves from value types to reference types its termed as 'Boxing' and the vice versa is termed as 'UnBoxing'.
