三个和尚升级版

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);
        System.out.println("input 3 number\n");
        int x = sc.nextInt();
        int y = sc.nextInt();
        int z = sc.nextInt();

        int a = 0;
        a = x >= y? x : y;
        int b = 0;
        b = a >=z ? a : z;
        

        System.out.println("max b:" + b);

    }
