Question

Which action must be avoided to prevent the previously-defined names from getting overwritten? Use the wildcard import?

Answer 1

Explanation:

Well, you did not post the real names of your class and members, but such things can happen more easily when some_info has an ambigous name, not making clear it's real purpose. So besides the other good answers here, try to avoid that, choose names which document the purpose of a variable more clearly, especially for member variables.

Answer 2

Using the Wildcard import action must be avoided to prevent the previously-defined names from getting overwritten.

Explanation:

• Web traffic data may be the most used of all web metrics tools. The request is received by your Web server.
• The wildcard imports all groups in a package using and the class knowledge in an imported bundle is not read in at the point of initialization or runtime unless the class is used within the application.
• The import statement simply tells the compiler where to locate the classes.
