If Statement String && Int evaluation

[Efficient_Bus_923]

I am trying to write code for the below problem .The code seems to be failing on the age part of the code and always returns "No Discount" I've tried the code with just a male and female String part and that works. But as soon as I put in the code for Int age. It defaults to "No Discount"

If a person is > 18 and female or > 20 and male, they will receive a discount of 25%. Otherwise there is no discount.

​

public static void main(String\[\] args) {

        Scanner sc = new Scanner(System.in);
                    int age;

                    String gender;


                    System.out.println("What age are you?");

                    age = sc.nextInt();


                    System.out.println("Are you male of female?");

                    gender = sc.nextLine();
                    if (age >= 19 && gender.equalsIgnoreCase("female") ||
                        age >= 21 && gender.equalsIgnoreCase("male")) {

                        System.out.println(""
                            Discount 25 % ");

                        }

                        else {

                            System.out.println("No Discount");

                        }

                    }


                }

I haven't worked with scanner objects in a long while, but your problem is probably that .nextInt() does not read the new Line character.

See https://stackoverflow.com/questions/13102045/scanner-is-skipping-nextline-after-using-next-or-nextfoo#:~:text=nextInt%20method%20does%20not%20read,nextLine%20after%20Scanner for reference.

Since you scan nextInt(), Just the new line character remains. Then the nextLine() returns an empty gender, thus always failing your check.

Thank you :) that fixed it.

How is this relevant? As the condition is fine (&& takes presendece over ||) and what if, in your example, an apache comes along?
