Given a double variable named areaOfSquare write the necessary code to read in a value , the area of some square, into areaOfSquare and print out the length of the side of that square.

LANGUAGE: JAVA

CHALLENGE:

NOTE: in mathematics, the square root of a negative number is not real; in Java therefore, passing such a value to the square root function returns a value known as NaN (not-a-number).

Given a double variable named areaOfSquare write the necessary code to read in a value , the area of some square, into areaOfSquare and print out the length of the side of that square.

HOWEVER: if any value read in is not valid input, just print the message “INVALID”.

ASSUME the availability of a variable , stdin, that references a Scanner object associated with standard input.
