All Implemented Interfaces:

Direct Known Subclasses:

public abstract class QTIException
extends java.lang.Exception

Superclass of all checked exceptions (currently not used anywhere).

It is abstract class because you should never use this class directly. For example:

 throw new QTIException()
 

(this is not possible anyway)

And you should never use this class in method header also. For example:

 void someMethod() throws QTIException
 

Only two legal usages are as superclass of all checked exceptions and in catch block, when you don't need to distinguish between different exceptions types. For example:

 try
 {
   ... some code here ...
 }
 catch (QTIException ex)
 {
   ... some code here ...
 }
 

Checked exceptions are reserved for special purposes. In general case you should use unchecked exception instead.
