private static void Booking()

or

public static void Booking()

 

[LonelyNinja]

indi po e. yun namn pong naka paloob na method sa booking() ang problema yung printSeat() at bookSeat().

 

[LonelyNinja]

ginawa ko na rin pong static lahat ng method ito namn po ang problema

Luh, bakit di ko alam yan? hahahaha nag jajava rin naman kami dati.

 

[zackmark29]

you can't call a non-static from static. Unless you create a new instance class

 

[zackmark29]

make your global variable a static as well
