Untuk membuat kelas pada project dengan Nama Februari_11:
Klik kanan mouse, klik new ada beberapa pilihan dan klik Java Class.
Sesudah
itu beri nama “Increment_Coba” (sesuka kalian beri nama apa)
Sesudah itu beri nama “ArithmeticDemo” (sesuka kalian beri nama apa)
contoh programnya:
public class ArithmeicDemo {
public static void main(String[] args) {
//beberapa angka
int i = 37;
int j = 42;
double x = 27.475;
double y = 7.22;
System.out.println("Nilai Variabel...");
System.out.println("Nilai Variabel...");
System.out.println(" i = " + i);
System.out.println(" j = " + j);
System.out.println(" x = " + x);
System.out.println(" y = " + y);
System.out.println("Penjumlahan...")
System.out.println(" i + j = " + (i + j ));
System.out.println(" x + y = " + (x + y));
//Pengurangan angka
System.out.println("Pengurangan...);
System.out.println("i - j = " + (i - j));
System.out.println("x - y = " + (x - y));
//Pengalian angka
System.out.println("Pengalian..."); System.out.println(" i * j = " + (i*j)); System.out.println(" x * y = " + (x*y));

//Pengurangan angka
System.out.println("Pengurangan...);
System.out.println("i - j = " + (i - j));
System.out.println("x - y = " + (x - y));
//Pengalian angka
System.out.println("Pengalian..."); System.out.println(" i * j = " + (i*j)); System.out.println(" x * y = " + (x*y));
//pembagian angka
System.out.println("pembagian..."); System.out.println(" i / j = " + (i/j)); System.out.println(" x / y = " + (x/y));
//perhitungan modulus (sisa pembagian)
System.out.println("perhitungan modulus...");
System.out.println(" i % j = " + (i%j));
System.out.println(" x % y = " + (x%y));
//perhitungan kombinasi Variabel
System.out.println("perhitungan Variabel"); System.out.println(" j + y = " + (j+y)); System.out.println(" i + x = " + (i+x));
