你的答案是什么？是下面的答案吗？
;
int b = 0;
try { // try监控区域
if (b == 0) throw new ArithmeticException(); // 通过throw语句抛出异常
System.out.println("a/b的值是：" + a / b);
}
catch (ArithmeticException e) { // catch捕捉异常
System.out.println("程序出现异常，变量b不能为0。");
}
System.out.println("程序正常结束。");
}
}
运行结果：;
int b = 0;
try {
System.out.println("a/b的值是：" + a / b);
} catch (ArithmeticException e) {
System.out.println("程序出现异常，变量b不能为0。");
}
System.out.println("程序正常结束。");
}
}
