Import Package in Java
Used to import a package with pre-defined features.
import packageName; //import entire package import packageName.member; //import member from package
The JDK includes many packages for use, but custom packages can also be imported using the IDE.
When only a few methods are used, it is best to import these methods individually. It is bad practice to import an entire package if only a few methods from the package are used.
import java.util.Scanner; //somewhere else in the code Scanner textScanner = new Scanner();
