Program operator-operator matematika

Dibawah ini adalah program sederhana yang mendemontrasikan operator-operator aritmatika

// Mendemonstrasikan operator-operator dasar aritmatik.

class MatDasar {

    public static void main(String args[]) {

        // aritmatik menggunakan integer

        System.out.println("Aritmatik Integer");

        int a = 1 + 2;

        int b = a * 3;

        int c = b / 4;

        int d = c - a;

        int e = -d;

        System.out.println("a = " + a);

        System.out.println("b = " + b);

        System.out.println("c = " + c);

        System.out.println("d = " + d);

        System.out.println("e = " + e);

        // aritmatik menggunakan double

        System.out.println("\nAritmatik Titik Mengambang");

        double da = 1 + 1;

        double db = da * 3;

        double dc = db / 4;

        double dd = dc - a;

        double de = -dd;

        System.out.println("da = " + da);

        System.out.println("db = " + db);

        System.out.println("dc = " + dc);

        System.out.println("dd = " + dd);

        System.out.println("de = " + de);

    }

}

Hasilnya:

run:

Aritmatik Integer

a = 3

b = 9

c = 2

d = -1

e = 1

Aritmatik Titik Mengambang

da = 2.0

db = 6.0

dc = 1.5

dd = -1.5

de = 1.5
