Java Scanner

Java compiler automatically imports two packages: java. lang and the current package . The Constants class is located in the same package as the AutomaticImports which is referring to its version member.

Using import * in python programs is considered a bad habit because this way you are polluting your namespace , the import * statement imports all the functions and classes into your own namespace, which may clash with the functions you define or functions of other libraries that you import.

I updated my answer to clarify. The * imports all classes and interfaces in the package .20 Ara 2012
