What are advanced generics in Java?
Advanced generics in Java refer to the use of generics beyond basic type parameters, including bounded type parameters, wildcards, and type inference.
Can you explain bounded type parameters?
Sure! Bounded type parameters allow you to restrict the types that can be used as arguments for a type parameter. For example, you can specify that a type parameter must be a subclass of a certain class or implement a specific interface.
What are wildcards in generics?
Wildcards are special types in generics that allow for flexibility. They are represented by the question mark (?) and can be used to denote an unknown type. There are three types: unbounded, upper-bounded, and lower-bounded wildcards.
How does type inference work with generics?
Type inference in generics allows the Java compiler to automatically determine the type arguments based on the context, reducing the need for explicit type declarations.
