Generics: This happens at compile-time. The compiler checks for the type correctness of the program and translates or rewrites the code that uses generics into non-generic code that can be executed in the current JVM. This technique is known as “type erasure”. In other words, the compiler erases all generic type information contained within the angle brackets to achieve backward compatibility with JRE 1.4.0 or earlier editions.
I have not understood clearly what it means.
Any links resources ideas highly appreciated. Thanks in advance
