Kelas : PBO -A
Kali ini saya mendapatkan tugas untuk membuat gambar sederhana menggunakan BlueJ. Setelah membaca berbagai sumber dan melihat tutorial di Youtube, akhirnya saya berhasil membuat sebuah gambar. (Ayeeee!).
Untuk membuat gambar sederhana versi saya, saya membuat 6 Class, yaitu :
- Pic
- Canvas
- Rectangular
- Circle
- Triangle
- Square
Berikut adalah Source Code nya
- Class Pic
