PieChart Java NetBeans

Bertemu lagi ,Der...!!
kali ini saya akan memberikan sedikit pengetahuan saya dengan membagikan code seputar pemrograman java object , kali ini saya menggunakan platform Java NetBeans IDE 8.1 jika belum punya alangkah baiknya untuk menginstall terlebih dahulu ,der....!!
silahkan download melalui website reminya : https://netbeans.org/

Maaf ,Der...!! saat ini saya tidak membahas cara menginstall NetBeans nya ,lain kali bila ada waktu saya share di sini .

Langsung aja deh topik utamanya untuk Membuat Object PieChart dengan Java NetBeans
Langkah-langkahnya :

1. Buatlah project baru ,misal : Latihan
2. Buatlah 2 Java Class ( beri nama Canvas.class dan MainPanel.class ).
