Explain Exception handling in JNI.There are two ways to handle an exception in native code:
-The native method can choose to return immediately, causing the exception to be thrown in the Java code that initiated the native method call.
-The native code can clear the exception by calling ExceptionClear (), and then execute its own exception-handling code. After an exception has been raised, the native code must first clear the exception before making other JNI calls. When there is a pending exception, the only JNI functions that are safe to call are ExceptionOccurred (),ExceptionDescribe (), and ExceptionClear (). The ExceptionDescribe () function prints a debugging message about the pending exception.
