"Why this is showing syntax error"??
Example.java contains a program using the GoKart class we have been building (included for you to reference).
Protect the call to kart.drive by handling the IllegalArgumentException that is thrown when not enough battery remains. Print out the message from the exception to the screen as you catch the exception.

The || operator means OR, < means less than, and > means greater than.
The statement can therefore be read as:
"42 is less than 40 OR 42 is greater than 50"
Since 42 is neither less than 40 nor greater than 50, the statement evaluates to False OR False = False.
