*When you use * in the import statement, which is a wild card, the javac
compiler goes and tries to search the class file relevant to you in the
package specified.
For eg:, for the statement
import java.io.*;
The javac compiler will go to the io package in java folder and try to
find out whether you are using 'File' or some other class file.
In contrast, when you say:
import java.io.File;
It knows, where it has to go. The use of wild card makes the process a bit
slower and its advisable that you use it only when you require the usage of
multiple class files from the same package.
