Java only get Exception name without StackTrace
提问by Broadwell
how can I get the exception name without getting the stack trace?
如何在不获取堆栈跟踪的情况下获取异常名称？
I am using exception.toString()to convert the thrown exception into a string, but I only want the exception name likeNullPointerExceptionand not the entire stack trace.
我正在使用exception.toString()将抛出的异常转换为字符串，但我只想要异常名称，NullPointerException而不是整个堆栈跟踪。
How can I solve this?
我该如何解决这个问题？
回答by Sergey Pauk
exception.getClass().getSimpleName();
NOTE: this will not work in case if your exception is an anonymous class (although I have personally never seen an anonymous exception in any production code)
注意：如果您的异常是匿名类，这将不起作用（尽管我个人从未在任何生产代码中看到匿名异常）
