Give me a code that calculates the triangle with if

ublic class Triangle {
    public static void main(String[] args) {
        int a, b, c;
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the sides of the triangle");
        a = sc.nextInt();
        b = sc.nextInt();
        c = sc.nextInt();
        System.out.println
