Advanced programming with Java generics
Briefly

Generics in Java enhance the type safety of your code and make it easier to read... By introducing type constraints and type inference, they streamline code and reduce errors.
Type inference, introduced in Java 7, allows the Java compiler to automatically determine or infer the types of parameters and return types based on method arguments and the target type.
Using generic methods with wildcards and bounded type parameters enhances flexibility in your code. It restricts the types used and allows for a more versatile approach to coding.
With type inference, you can write cleaner code by eliminating unnecessary type repetition. This not only improves readability but also decreases the risk of runtime errors.
