I am trying to find the maximum and minimum of 5 inputs. This code works perfectly but can it be simplified? It seems very excessive but I have only just started programming in Java so I haven't learnt much yet. I am also only allowed to use if statements. No loops.

CodePudding user response：

Try this.

static void maxMin(String name, double f, double g, double h, double i, double j) {
    if (f > g && f > h && f > i && f > j)
        System.out.println(name   " is max");
    else if (f < g && f < h && f < i && f < j)
        System.out.println(name   " is min");
}

public static void main(String[] args) {
    Scanner myInput = new Scanner(System.in);
    double a, b, c, d, e;
    a = myInput.nextDouble();
    b = myInput.nextDouble();
    c = myInput.nextDouble();
    d = myInput.nextDouble();
    e = myInput.nextDouble();

    maxMin("a", a, b, c, d, e);
    maxMin("b", b, c, d, e, a);
    maxMin("c", c, d, e, a, b);
    maxMin("d", d, e, a, b, c);
    maxMin("e", e, a, b, c, d);
    if (a == b || a == c || a == d || a == e || b == c || b == d || b == e || c == d || c == e || d == e)
        System.out.println("Identical integers detected");
}
