<div>
In simple words, its like the base class to the derived classes. Common functionality is moved to the base class, and only extra (remaining) one can be placed in the derived class.<br />

<div>
they mean that two methods which essentially are implemented in the same way with the only difference<br />
that different type is used - then it is the case where generics would allow you to reuse the same code,<br />
evben though without the generics you'd have to write a separatr version of the code for each type<br />

What does the word implementation mean with regards to generics?

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
