you will implement the isValid static method in the sysImplementation package. The code for the SampleDriver

class is given to you. Regarding the code you need to implement:

$$ You don$$t need to add comments to your code, but you must have good style $($variable names, indentation, etc.$)$

$$ During the implementation of the class $,$ you should not add any fields $($instance and static member variables$).$ Just code

up isValid. Adding local variables and private helper methods are allowed.

$$ Delete the exception in isValid and code up the solution.

$$ You may use any library method as long as it does not need an import statement.

isValid Specification

If it is not a $4$ X $4$ integer array throw the IllegalArgumentException with the argument: Invalid Parameter. Think about all

possible ways it could not be a $4$X$4$ int array and yet still compile.

If each row, each column, and both diagonals of the array each add up to $34,$ return true. Otherwise, return false.
