Answer 1

Functions:

• Generic types can represent only reference types, not primitive types.

Bounded types

• Declare the type Parameter <t> followed by the extend word, followed by the upper bound:</t>
  
  • ​<t>&gt;</t>

Generic class

• We can define several generic types
• <t> follows the name of the class</t>
