帮忙看看这段java代码，关于boolean用法不是很清楚

Question

public static boolean isDrinkOrNot(int flag)

{

boolean judge = false;

if(flag==1){judge = true;}

return judge;

}

public static double drinkPrice(double num, boolean drink)

{

double totalDrinkPrice;

if(drink){totalDrinkPrice = 20*num;}

else{totalDrinkPrice = (5*num)*0.95;}

return totalDrinkPrice;

}

//最好能解释一下这段代码，初学，表示有些看不懂。。。非常感谢各位大神啦~

Answer 1

public static boolean isDrinkOrNot(int flag)//flag为1为喝酒了，0为没喝酒{boolean judge = false;//默认状态是false，应该就是表示没有喝酒if(flag==1){judge = true;}//喝酒了，所有judge变truereturn judge;//最终返回judge，true为喝酒了，false为没喝酒，由传入的flag控制}public static double drinkPrice(double num, boolean drink)//返回喝的酒的价格，drink应该表示喝没喝，具体得看题目{double totalDrinkPrice;if(drink){totalDrinkPrice = 20*num;}//drink为true,则用这种方式计算总价else{totalDrinkPrice = (5*num)*0.95;}//drink为false,则用这种方式计算总价return totalDrinkPrice;//返回总价格}因为没有题目所以解释的可能会不太符合题意望采纳~

Answer 2

public static boolean isDrinked(int flag){ return flag ==1; } public static double totalPrice(double num,boolean flag){ if(flag) return 20*num; else return 5*num*0.95; } 手机编写。这样写我心里好受些。

Answer 3

其实不用boolean也行，用int的0和1也一样的效果。
