Selamat datang ke Post Tutorial POS DENGAN JAVAX . Disini akan membuat sebuah tutorial tentang bagaimana membuat program pertama kali pada aplikasi BlueJ. BlueJ adalah IDE yang dibuat untuk media pengajaran java. IDE ini dikembangkan oleh Michael Kollin pada tahun 1999 hingga sekarang dibantu dengan ORACLE.

BlueJ juga merupakan program opensource yang berada dibawah lisensi GNU GPL versi 2.
