编写Main类，用scanner类输入两个整数a，b；采用Java异常处理机制（try...catch 语句）处理以下异常： 1. 如果a，b不是整数(InputMismatchException)，输出java.util.InputMismatchException was thrown 2. 如果b是零(ArithmeticException)，输出：java.lang.ArithmeticException was thrown 3. 无异常抛出，则打印输出a/b样例输入 6 3 样例输出 6/3=2

以下是代码实现：

import java.util.InputMismatchException;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        try {
            int a = scanner.nextInt();
            int b = scanner.nextInt();
            int result = a / b;
            System.out.println(a + "/" + b + "=" + result);
        } catch (InputMismatchException e) {
            System.out.println("java.util.InputMismatchException was thrown");
        } catch (ArithmeticException e) {
            System.out.println("java.lang.ArithmeticException was thrown");
        }
    }
}

运行结果：

输入：

6 3

输出：

6/3=2
