Erasure:

If generic code is encountered by java compiler, it uses the process called “erasure” to compile the code.

As the name implies, the generic notation are erased by the compiler, and the actual type is substituted for each type parameter.

When generic class, interface, or method with an unbound type parameter such as <T>, o...
