Question

how can I import a file in java programming language

Answer 1

If by import a file you meant read a file, there are several ways, probably the most common of which are using the Scanner and BufferedReader objects. Have a look at
http://java.sun.com/javase/6/docs/api/java/util/Scanner.html
and
http://java.sun.com/javase/6/docs/api/java/io/BufferedReader.html
respectively for information on how to use them.
