1. Latar Belakang Grafik vektor banyak sekali digunakan pada pembuatan game-game 2 Dimensi dimana terdapat banyak method-method yang sudah disediakan oleh Java seperti ketika kita ingin menangani pengujian tabrakan, menampilkan bound berupa rectangle dan masih banyak lagi. Grafik vektor merupakan pelajaran dasar yang harus dipelajari sebelum memasuki pembahasan grafik bitmap. pada bab ini juga dibahas masalah tentang penanganan grafis full screen dimana game yang akan kita buat dapat dimainkan dalam satu layar penuh. 2. Tujuan Setelah mempelajari lab activity ini peserta diharapkan dapat: Mengetahui fungsi dari class Shape. Menggambar garis menggunakan class Graphics2D. Mengetahui perbedaan antara Rectangle2D dan RoundRectangle2D. Menggambar menggunakan Arc2D. Memahami fungsi dari Polygon. Membuat tampilan mode Full-Screen Menjalankan dan menutup mode Full-screen 1 Page
