Java Generic Learning Notes-(v) Generic interfaces

The so-called generic interface, similar to a generic class, is to define generics on the interface, in the following format:
　　Public interface Interface name < type parameters >
Such as:

1 Interface Inter<t> {2public     void  show (T t); 3 }

There are two ways to implement it:
1. Specify generics at implementation time:

1 class Implements Inter<string> {23    @Override4      public  void  Show (String t) {5        System.out.println (t); 6     }7     8 }

2. When instantiating, specify the generic type:

1 class Implements Inter<t> {23    @Override4public     void  Show (T t) {5        System.out.println (t); 6     }7     8 }

Call:

1 New A (); 2 a.show ("hi!" ); 3 New B<>(); 4 b.show (true);
