如何在不引发异常的情况下捕获块

Question

I have a java class which is throwing IOException .I have some code in Catch block which i need to debug. I don't know in which case my java class is throwing exception. So I need to go to catch block explicitly without throwing. Can it be possible.

Please help me out.

Answer 1

Control wont goto catch block if exception is not thrown. Put the code in finally block which you want to execute irrespective of whether exception thrown or not.

Sample:

try {

} catch() {

} finally {
//Put code here
}

Answer 2

Code in a catch block is not executed if no matching exception is thrown in the try block.

The only way to execute it is to cause the IOException to be thrown.

You can just put an explicit throw new IOException(); as the last line in the try block.

Alternatively, you might be able to pull the contents of the catch block into a separate method, which you can then invoke explicitly.

但是如果引发了异常，您将被定向到finally块，或者可以发布示例代码，这样可能会对您有所帮助
