HASIL PROGRAM SETELAH DIJALANKAN :
6. CARA COPY PROGRAM SUPAYA BERJALAN
1. buat project baru pada netbeanst dan beri nama "vektor project" atau boleh bebas.2. Penting, jangan rubah apapun pada tulisan "package.....bla bla bla" dan "public class ... bla bla"
3. copy script dibawah ini pada baris bawah setelah "package ..bla bla bla".
