Belajar Array Pada Bahasa Java part 1

1. Buat program dengan tipe java

2. int i merupakan deklarasi i sebagai interger
3. Kemudian kita buat array dengan nama dataku dengan jumlah 5 array
4. for merupakan untuk perintah looping pada program
5. i=0 berarti sama saja i tidak mempunyai nilai
6. nilai i kurang dari dataku
7. i akan berbentuk angka
8. Math.random untuk memunculkan angka dengan nilai 0.0XX x 100 = XX
9. dataku dikeluarkan dengan menambah angka 1
10. Sebenarnya dataku merupakan array 0-4 atau kurang dari 5
11. dengan program i+1 dataku yang semula 0-4 angka 0+1 dan hasilnya angka 1 dan seterusnya bisa di lihat pada hasil program.
