catch(ArithmeticException ae){ System.out.println("系统正在维护,请与管理员联系!"); ae.printStackTrace(); } finally { System.out.println("catch成功!"); } } } 运行结果如下: throw和throws的区别 throw: 1.throw是语句抛出一个异常 2.出现在函数体中 ...
System.out.println("发生空指针异常: " + e.getMessage()); } 在上面的例子中,我们尝试将字符串”abc”转换为整数,这会抛出一个NumberFormatException。如果字符串不能转换为整数,则可能会抛出NullPointerException。使用多个catch块可以分别处理这两种类型的异常。三、总结通过使用try-catch块和多个catch块,我们可以...
