What does “The type ArrayList is not generic” mean?

Question

I am new to Java and trying to learn the various collections that programmers can use. I imported \"java.util\" into a scrapbook in Eclipse and inspected the following code.

Answer 1

What comes into my mind:

• check if the JDK is fully compliant with generics (so that the ArrayList class in your JSE is actually a generic class)
• check if you don't have another ArrayList which has scope precedence and overrides the standard library definition
