异常处理之多重catch

package com.sxt.exception.test1;

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

/*
 * 异常处理之多重catch
 * ArrayIndexOutOfBoundsException：数组越界异常
 * ArithmeticException：算术异常
 * InputMismatchException：输入类型不匹配异常
 * 
 * 多重catch时需要考虑异常的子父类关系 子类在上 父类在下
 * 执行顺序：try语句块->相应的catch语句块-->finally语句块-->执行到最后
