Java package keyword example

In Java, the package keyword is used to specify a directory structure to which the current source file must belong. For example:

package com.mycompany.code;

public class MyClass {
}

In the above example, the source file MyClass.java must be placed under the directory /com/mycompany/code

Here are some rules regarding the package statement:

• • a source file can be put under a package or not.
  • the package statement (if specified) must be the first line in the source file.
  • package name must follow the pattern: level1.leve2.level3....leveln
