Contoh cara pemanggilannya dapat secara langsung karena bersifat statis:
System.out.println(" Hostname = " + NetworkInfo.hostName());
System.out.println(" IPAddress = " + NetworkInfo.ipAddress());
System.out.println(" MacAddress = " + NetworkInfo.macAddress());

If there is darkness in this world...
then there is the trap called "the light"
One after another with these hands I expose and destroy them
The strong surely believe in what is right
"Fate" is the excuse of the weak

Fight for justice
It's not for anyone else
I just want to prove my way of life
Fight for justice
If it is for justice...
...then I'm willing to sacrifice it all

Is it black or white ?
I only believe in the truth I see with my own eyes
If I listen to others, it'd create hesitation in me
The peaceful town is being threatened someone with the potential for more
No one can forgive that judgement!

Fight for justice
I want to prove I am
a more worthy soldier than any other
Fight for justice
To make it through
I'd be willing to sacrifice it all

The wind hits me strongly
It almost stops this thirst in my heart
I'm still not close enough to perfection
My irritated heart, desires justice

Fight for justice
It's not for anyone else
I just want to prove my way of life
Fight for justice
If it is for justice...
...then I'm willing to sacrifice it all

1. Tekan Alt + F2

3. Cari bagian yang tertulis "End Default Options"
   
4. Edit berbagai setting yang tersedia (contoh: Title adalah judul pada menu)
   
5. Untuk menghilangkan menu pada saat booting dapat dengan menghapusnya atau memberi tanda '##' untuk menandainya sebagai komentar
6. lalu simpan sehingga berubah
   
   
7. Ohya kadang terdapat kegagalan ketika menyimpannya. Lebih baik masuk sebagai Super User.
8. Untuk menjadi super user, ketik : sudo su
9. Masukkan password
10. Untuk mengedit boot menu ketik : /boot/grub/menu.lst
