The Integer. parseInt() method requires a String argument, but fails if the String cannot be converted to an integer and throws a NumberFormatException.

Write an application that takes an input from the user and feeds it into the parseInt method. If the input is invalid then catch the exception (NumberFormatException) and use the resumption model (Example 4.7c) to re-ask the user until a valid input is entered.

After a valid input is entered, display the square root of the number in a frame. Create a 500 by 500 frame and display the result in the paint method.

-Make the frame background blue

-The font should be SansSerif, size 18, italic and bold. The color should be red.
