java.lang.reflect.InvocationTargetException is an exception that is thrown when an error occurs while invoking a method or constructor through reflection. This exception is a checked exception and extends the Exception class.
The InvocationTargetException is thrown when the method or constructor being invoked through reflection throws an exception. The InvocationTargetException wraps the exception thrown by the method or constructor and provides additional information about the invocation.
The most common cause of the InvocationTargetException is when the method being invoked throws a checked exception that is not declared in the method signature. This is because the reflection API requires that all checked exceptions be caught and handled appropriately.
To handle the InvocationTargetException, the application should catch it and then call the getCause() method to retrieve the original exception that was thrown by the method or constructor being invoked. The application can then handle the original exception as appropriate.
