Generic collection list<t>

List<t> Generic Collection features:

• <T> represents generics, T is a type shorthand, indicating that the specific type is currently indeterminate;
• According to the actual needs of the user, the current collection needs to determine the type of data to be stored, once the determination is not changed;
• only one type of data can be added using a generic collection, and no casting is required after the data is taken out
