constant variables questions

[sgthale]

I have this final final short named 40 and its always constant no matter what. Is there a way so ALL of the classes share this variable?Because currently i have to put final short blah = 40; at the beginning of all my dam classes and its making my code so messy. Help!

You can declare it in a class as public static final short = final. Some other things you can think of is the PI constant supplied by the class Math.

It is declared as

public static final double PI = 3.141592....

If you add that short to a class you can import the package and use it as

ClassName.CONTANT_NAME

how to import?

[sunde887]

You have to package your class with the constant first, than import the class.

Using Package Members (The Java™ Tutorials > Learning the Java Language > Packages)

Creating and Using Packages (The Java™ Tutorials > Learning the Java Language > Packages)


Basically, you create a class and make the first line

package directoryName

As an example, I have written a class which is in the texteditor/actions directory, and the first line of all the files in this folder is

package texteditor.actions

Then I have some other classes which rely on the classes in the directory texteditor/actions. I gain access to them in other files with this line

import texteditor.actions.*;

You will have to package a class with the constants and then import it when necessary.
