Question

How to import

Answer 1

The concept of import in java came from the concept of the package in java. As we know packages provide the organized structure to our projects. We can define related classes or interfaces in similar types of packages. But we need to use the import statement in the program to use them.

Suppose we are working one a big project and managing your classes or interfaces through the packages. We can keep the utility class or common functionality in separate packages so that whenever we need it, we can you. To use that utility class, you will tell the compiler by use of the import statement.
import packageName.*;
