Problem 2: Safe Square Root Write a program to take the square root of a number typed in by the user. Your program should use a while-loop to ensure that the number they typed in is positive. If the number is negative, you should print out a warning “The number is negative. Try again.” and re-prompt the user to take a valid input. You can get the square root of a number n with Math.sqrt(n). Make sure you don't do this until the loop is done and you know for sure you've got a positive number. Sample input and output:   Enter a number > -9 The number is negative. Try again. Enter a number > 9   The square root of 9 is 3.0   Enter a number > 2   The square root of 2 is 1.4142135623730951

Problem 2: Safe Square Root

Write a program to take the square root of a number typed in by the user. Your program should use a while-loop to ensure that the number they typed in is positive. If the number is negative, you should print out a warning “The number is negative. Try again.” and re-prompt the user to take a valid input.

You can get the square root of a number n with Math.sqrt(n). Make sure you don't do this until the loop is done and you know for sure you've got a positive number.

Sample input and output:

 

Enter a number > -9

The number is negative. Try again.

Enter a number > 9

 

The square root of 9 is 3.0

 

Enter a number > 2

 

The square root of 2 is 1.4142135623730951
