Answer 1

Those classes are marked as @Deprecated.

This means that the compiler advises not to use them, because they can bring you problems.

A program element annotated @Deprecated is one that programmers are discouraged from using, typically because it is dangerous, or because a better alternative exists. Compilers warn when a deprecated program element is used or overridden in non-deprecated code.

Check the javadoc(s) of the deprecated classes to check which classes to use instead.
