public class Ngoding {
    public static void main(String[] args) {
 // for luar untuk banyak baris (1 ~ 5)
 for(int i = 1; i <= 5; i++) {
     // for luar untuk banyak kolom (1 ~ i)
     // jadi saat pengulangan pertama [i = 1], maka (1 ~ 1)
     // saat pengulangan kedua [i = 2], maka (1 ~ 2), dst...
     for(int j = 1; j <= i; j++) {
  System.out.print("*");
     }
     System.out.print("\n");
 } 
    }
}

Kesimpulan

1. Variabel Inisialisasi
2. Kondisi (saat kapan pengulangan bisa dijalankan)
3. Update Variabel
   Dalam contoh kita hanya membuat i++, j++. Tetapi kita bisa melakukan hal lain juga, bukan hanya increment 1 nilai.
   i++; sama saja dengan i += 1; atau sama saja dengan i = i + 1;
   Hal ini termasuk kedalam penggunaan Operator Inisialisasi.
   Seperti  i += 2; berarti i = i+2;
