Only those exceptions that are subclasses of RuntimeExceptionare considered unchecked.
只有属于 的子类的那些异常才被RuntimeException视为未检查的。
Yours isn't, and therefore is a checkedexception.
你的不是，因此是一个检查异常。
回答by Masarrat Siddiqui
It's a checked exception class. Any class which extends Exception class will be a user defined Checkedexception class. Where as any class which extends RuntimeException will be Uncheckedexception class.
这是一个检查异常类。任何扩展 Exception 类的类都将是用户定义的Checked异常类。任何扩展 RuntimeException 的类都将是Unchecked异常类。
回答by Surya
User Defined exceptions are checked exceptions because they are extended with Exception class which is super class for all the exceptions occured,where as unchecked exceptions are extended with run time Exceptions.
用户定义的异常是已检查的异常，因为它们扩展了 Exception 类，该类是所有发生的异常的超类，而未检查的异常则扩展为运行时异常。
回答by B_Ali_Code
THere are two classes call as partially checked exception.
有两个类作为部分检查异常调用。
1.) Exception class
1.) 异常类
2.) throwable class
2.) 可抛出类
It calls partially checked because some of their subclasses are Unchecked. So you have extended the Exception class then it's Checked exception
它调用部分检查，因为它们的一些子类是未检查的。所以你已经扩展了 Exception 类然后它是 Checked 异常
回答by Snicolas
You could have used IllegalArgumentException.
您可以使用IllegalArgumentException。
This exception is unchecked whereas yours is checked as @duffymo & @aix commented.
这个异常没有被检查，而你的异常被检查为@duffymo & @aix 评论。
