Program Java sederhana Menghitung nilai Rata-Rata

Baik lah saya akan sedikit berbagi tentang cara membuat program sederhana java mengitung nilai rata-rata.

Desc.
- terdapat 4 variabel yang akan di input
- output akan menampilkan hasil nilai rata- rata dari 4 variabel tersebut.

Komponen
- float
- int
- string
- for


Berikut Source Code .
public class UTSALGO2 {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        float [ ] nilai =  new float[4];
        float jumlah, nilairatarata;
        int i;
       
        for (i = 0; i < 4; i++)
        {
            String bilangan = JOptionPane.showInputDialog("Masukkan nilai:");
            System.out.println("Input angka: " + bilangan);
            nilai[i] = Float.parseFloat(bilangan);
        }
       
        jumlah = 0;
        for (i = 0; i < 4; i++)
            jumlah = jumlah + nilai[i];
        nilairatarata = jumlah/ i;
        System.out.println("Nilai rata-rata ="+" "+ nilairatarata);
       
        System.exit(0);
      
        }   
    }


dan berikut hasil Outputnya































 Hasil akhir .
