The main program calls a method validGroup$()$ to determine if this

set of three values forms a valid group. The method validGroup$()$

receives four parameters $($the $3$ scores and a file object$).$ For the group

to be valid, each number must be in the range from $0$ to $300($the

possible scores in a bowling game$).$ If the group is valid, the method

prints a message saying so$.$ If one or more of the numbers is negative

or greater than $300,$ the method prints an overall message that the group

is invalid. In addition, for each invalid value, the method prints the

score and a message why the score is invalid. The method returns a

boolean value $($true or false$)$ as a signal indicating the validity of the

group. $($Hint: use six $$if$$ statements.$)$

If the group is not valid, the main program skips processing and

simply goes on to the next group of three scores.
