一个java小游戏

public static void main(String[] args) { Scanner reader=new Scanner(System.in); int area; System.out.println("Game Start…………Pleaseenter the area:(1-9)"+ '\n'+"1,2,3 means easy"+'\n'+"4,5,6 means middle"+'\n'+"7,8,9 means hard"+ '\n'+"Please choose:"); area=reader.nextInt(); switch ((area-1)/3) { case 0: System.out.println("You choose easy! "); break; case 1: System.out.println("You choose middle! "); break; case 2: System.out.println("You choose hard! "); break; } System.out.println("Good Luck!"); GameProcess game1=new GameProcess (area); game1.GameProcess (area); } }
