Write a user defined function called Fun$\_$ValueRef$\_$Param that returns a boolean type and takes $2$ integer parameters $($x and y$).$ The parameter x is passed by value and y is passed by reference. The variable y is changed to a number $($say $100).$ If the sum of the value of parameter x and newly updated value of y is negative then the function returns false otherwise returns true.

Also write the statement to call the function created above in the main method $-$ assume that this function is a member of class named Class$1.$
