How do Java generics affect performance?

How do Java generics affect performance?

Java generics provide type safety and code reusability, but they can also introduce some performance overhead due to type erasure.

What is type erasure in Java generics?

Type erasure is the process by which the Java compiler removes all generic type information during compilation, replacing it with raw types.

Does using generics slow down my application?

In most cases, the performance impact is minimal. However, if you're using generics extensively in performance-critical sections, it might be worth profiling.

Are there any best practices to optimize performance with generics?

Yes, avoid unnecessary boxing and unboxing, and prefer using primitive types when performance is critical.
