"Finally block does not complete normally" warning resolution

Reprint Address: http://www.cnblogs.com/interdrp/p/4095846.html

Java inside is not guaranteed to finally will be executed, why not in finally block to do return.

To look carefully:
Debug this function, you will be surprised to find that the exception thrown inside will be finally eaten. That's why they're being warned.

@SuppressWarnings ("finally")
private Boolean isreturnwithinfinally ()
{
	try {
		if (true)
			throw New RuntimeException ();
	} Finally {return
		(TRUE);/* This hides the exception */
	}
}

So, the following is OK. Deal with the exception first

public static void Main (string[] args)
{
	try{
		throw new RuntimeException ();
	} catch (Exception e) {/* */
	}
	finally {return
		;}
}

The conclusion is: Still not. The exceptions in Java are divided into two classes that are not captured and cannot be captured, even if the catch block is used, which can result in a catch-only error being eaten.
Therefore, return must be put to finally outside.
