Hi guys,
Why the following code:

Produce a compile error?
If change implements by extends, the code will compile but I don't understand why... is the Comparable an interface or not?
Thanks

Hello Rodolfo Mendoza
In the Above Code, Generics has been used ,According to rule of generics,
when we use Generic class or WildCard, keyword should be extends, even if it is implementing an interface, there is nothing called implements while dealing with generics

Hope i cleared you

thanks
