Hello,

I have for example the code i attached,
I think that if A.DeleteItem causes an exception, it should be caught in
Doit_subexample, isn�t it? In Init() there isn�t any try, catch.
I have a code similar to this I attached, an the exception isn�t
catched. Why?

class sub_example
{
private void Execute() throws Exception
	{
	//This method could throw an exception.....
	A.DeleteItem(item);

	}

public void Init() throws Exception
	{
	...
	Execute();
	....
	...
	}
}

class main_example
{
public void Doit_subexample
	{
	try
		{
		sub_example.Init();
		}
	catch(Exception e)
		{
		e.printStackTrace();
		}
	}
}

Thanks

Your assumption about your code is correct.  However, it is possible to 
bypass this if the error being thrown descends from java.lang.Error rather 
than java.lang.Exception; both of them have as their base class 
java.lang.Throwable.  A java.lang.Error, however, indicates a serious 
error, one that your application is not expected to recover from.
