$//$ write a static method named problem$2.$ Give a while loop to keep asking the user for floating point values. When the user

$//$ enters "stop" this loop should be terminated. THrow IllegalStateException if the user enters an integer value

$//($the value of the fractional part is $0).$ find the float$-$point value with the largest fractinal value then return it

$//$ Test case: if the entered values are $10\mathrm{.}5,25\mathrm{.}9,5\mathrm{.}558,112\mathrm{.}33,$ and $1\mathrm{.}352,$ return $25\mathrm{.}9$
