class Arithmetic public static void mainString args int

Εκτέλεση απλών αριθμητικών πράξεων. Ένα πρώτο απλό παράδειγμα με ακέραιους αριθμούς: class Arithmetic { public static void main(String args[ ]) { int x = 17, y = 5; System. out. println("x = " + x); System. out. println("y = " + y); System. out. println("x + y = " + (x + y)); System. out. println("x - y = " + (x - y)); System. out. println("x * y = " + (x * y)); System. out. println("x / y = " + (x / y)); System. out. println("x % y = " + (x % y)); } } Τετάρτη, 22 Δεκεμβρίου 2021 Γεωργιάδης Ζαφείρης

Πράξεις με boolean – τελεστές class Relational { public static void main(String args[]) { int x = 7, y = 11, z = 11; System. out. println("x = " + x); System. out. println("y = " + y); System. out. println("x < y = " + (x < y)); System. out. println("x > z = " + (x > z)); System. out. println("y <= z = " + (y <= z)); System. out. println("x >= y = " + (x >= y)); System. out. println("y == z = " + (y == z)); System. out. println("x != z = " + (x != z)); } Τετάρτη, 22 Δεκεμβρίου 2021 Γεωργιάδης Ζαφείρης }
