编写一个JAVA程序，要求用户输入两个整数num1和num2，然后输出它们的和、差、积、商、余数、平均数和最大值。

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入两个整数：");
        int num1 = scanner.nextInt();
        int num2 = scanner.nextInt();
        int sum = num1 + num2;
        int diff = num1 - num2;
        int product = num1 * num2;
        int quotient = num1 / num2;
        int remainder = num1 % num2;
        double average = (double)(num1 + num2) / 2;
        int max = num1 > num2 ? num1 : num2;
        System.out.println("和：" + sum);
        System.out.println("差：" + diff);
        System.out.println("积：" + product);
        System.out.println("商：" + quotient);
        System.out.println("余数：" + remainder);
        System.out.println("平均数：" + average);
        System.out.println("最大值：" + max);
    }
}
