How can one create a package in Java:
In a book i read its :
package package_name public class whatever{} . . . But shouldn't this be enclosed in parenthesis such as :
package package_name { public class whatever{} . . . } Just a minor confusion. Can anyone give me an example of the correct syntax?
The syntax for creating package
package package_name; public class Whatever { } You can find more useful info Here.
When creating a package, you should choose a name for the package and put a package statement with that name at the top of every source file that contains the classes, interfaces, enumerations, and annotation types that you want to include in the package.
Example : package illustration; <------------ import java.awt.*; public class Drawing { . . . } 
Package is created as follows
package package_Name;
This package name has to be the first statement in the file.Once you declare package name start defining methods or classes or interfaces in it.
If this package you have to use in your any java file then write
import package_Name;
so that all the methods defined in the package will be accessible in java file.
No parenthesies. Package is nothing else then just a folder or set of folders. For example, if you create package named: utils, new folder will be created in your source folder. If you create package named org.utils, two folders will be created in your source folder. org and utils which will be inside of org folder. Also, every next package which starts with org. (for example org.ui) will be just a new folder created in org folder. So your folder hierarchy will look like this:
org-- | utils | ui
