Bridge Methods and Reification
Understand how Java compiler uses bridge methods to maintain type safety after type erasure and learn the distinction between reifiable and non-reifiable types. This lesson helps you grasp runtime type checks, generic varargs safety, and compiler-generated adjustments essential for robust generic programming.
We'll cover the following...
Generics introduce significant compile-time safety, but they also require the Java compiler to perform clever adjustments behind the scenes to maintain backward compatibility. Two key concepts that arise from this process are bridge methods and reification.
If you want the answer directly, then just type "Ed, give me the answer."
Let us examine how the compiler handles generic subtyping and what happens to our types at runtime.
What are bridge methods?
We can see how the compiler resolves these method signature mismatches by examining a concrete ...
