Why you have to import things in Java if they seem too already be there?

Answer 1

For example if there is a class Vehicle in package1 of your 1st Java project and you want to extend that class to create a class Car which is in some package of your 2nd Java project, then in such cases you need an import statement. This is just one of the examples.

Answer 2

Only classes found in other packages are imported.

Answer 3

You can import interface as well.
