Editing Java syntax (section)

===Packages===
Packages are a part of a class name and they are used to group and/or distinguish named entities from other ones. Another purpose of packages is to govern code access together with access modifiers. For example, <code>java.io.InputStream</code> is a fully qualified class name for the class <code>InputStream</code> which is located in the package <code>java.io</code>.

A package is declared at the start of the file with the <code>package</code> declaration:

<syntaxhighlight lang=Java>
package myapplication.mylibrary;

public class MyClass {
}
</syntaxhighlight>

Classes with the <code>public</code> modifier must be placed in the files with the same name and {{mono|java}} extension and put into nested folders corresponding to the package name. The above class <code>myapplication.mylibrary.MyClass</code> will have the following path: <code>myapplication/mylibrary/MyClass.java</code>.
