java - 如何将 if-else 语句变成 switch 语句？

Question

这是我的 if-else 语句:

public static void main(String[] args) {

        Scanner input = new Scanner (System.in);
        int number;
        System.out.println("Enter Integer: ");
        number = input.nextInt();
        if (number % 7 == 0) {
                System.out.println(number + " is divisible by 7");
        }
            else {
                System.out.println(number + " isn't divisible by 7");
        }
    }

Answer 1

不用介意开关 - 你也不需要。
您可以将其放入一个语句中:

System.out.println(number + " is" + (number % 7 == 0 ? "" : "n't") + " divisible by 7");
