static import

[j bande]

hi every one i don't have clear idea on static imports can anyone help me.....

[Vassili Vladimir]

Hi,

Simply, use it when you are about to use the static member(s) of a class.

As an example, instead of saying:

    
System.out.println(Math.sqrt(4.0));

You can simply say:

    
import static java.lang.Math.sqrt;
import static java.lang.System.out;
 
// Then somewhere in your code, you say
out.println(sqrt(4.0));

Because both, the sqrt and System.out, are static members.

Best of luck ...

Another User Of Static Import.

Suppose you had imported.
import java.util.*;
import java.sql.*;

And now what happen if you try to make a object of Date Class? The Compile will confuse, which Date class to be used to create a Object either from util or sql. At that time you can tell compiler implicitly the name of Class.
like This,
static import java.util.Date;
import java.sql.*;


I hope I am making my self Clear.

I have a question.
Can we use import keyword in the package statement?
I really wonder if we can do that.

We are still required to mention the class name, and this is where the new feature of static import comes in. JDK 1.5 adds the ability to import the static members from a class, or the enum values from an enum type. It is analogous to the ordinary import statement, and it looks like this:



import static qualified_class_name.*;
