Algoritma': March 2014

Hello guys, Minggu ini adalah minggu ke 3 gw Tugas bikin BLOG :D
Materi untuk hari ini adalah LOGIC, yaitu :

1. Selection : if dan switch
2. Iteraction : for, while, do while
3. Modular = Method

Penjelasan :

1. ( Selection ) Bedanya IF dan Switch, yaitu :

IF : bisa pake string
Switch : hanya pake angka dan karakter

Berikut merupakan tabel dari 'Use Conditional' :

2. ( Interaction ) For, While, Do While :

- While : Program di cek terlebih dahulu baru dijalankan.

Bentuk Umum:
while(kondisi){
statement;

}

- Do While : Program dijalankan lebih dahulu baru di cek

Bentuk Umum:
do{
statement;

}

- For : Digunakan untuk melakukan perulangan yang didasarkan atas nilai diskrit misalnya integer.

Bentuk Umum:
for(inisialisasi;kondisi;perubahan){
statement;
}

Contoh Quiz untuk minggu depan 'Comand Pembuatan Mesin ATM'

}

Adalagi Contoh 'Comand Bintang.Java' :

public class Bintang{
    public static void main( String args[] ){
        //baris x kolom
        for(int i=0; i<10; i++){
            for(int j=0; j<=i; j++){
                if(j==0 || j==i || i==9){
                    System.out.print(" ");
                }else{
                    System.out.print("*");
                }
            }
            System.out.println();
        }
    }
}

Cukup pusing bukan ? :D haha apalagi Comand ATM :D yaudah, sekian BLOG ane hari ini. Maaf kalo kurang lengkap :D
