How do I write package names in Java?

While choosing a package name you need to keep the following points in mind.

• The name of the package should be in small letters.
• It is suggested to start the name of the package with the top level domain level followed by sub domains, ex: com.example.tutorialspoint.

Example

You can declare a package as in.

package com.mypackage.tutorialspoint;
Public class Sample {
   Public static void main(String args[]) {
      System.out.println("Welcome to Tutorialspoint");
   }
}

Executing a package

You need to compile the file with packages using –d option as:

C:\Sample>javac -d . PackageExample.java

After compiling, you can see the class files of the class created in the location com/mypackage/tutorialspoint.
