Assignment: #NearestSquares Due: 04/07/02019 Points: 3

### Specification

The program prompts the user to enter a positive integer and reads the input into an int defined variable. This specification assumes the variable is named n.

Print an error message and exit the program if n is less than zero.

If n is a square number, print a message saying n is a square number along with its square root and exit the program.

Print the difference between n and its nearest square number that's less then n and the difference between n and its nearest square number that's greater than n. In addition, print the two nearest square numbers along with their respective square roots.

Example inputs/outputs. [Note: User inputs are in bold.]

```   Enter a positive integer: 2001
-65...24 [sqrt(1936)=44...sqrt(2025)=45]

Enter a positive integer: 71
-7...10 [sqrt(64)=8...sqrt(81)=9]

Enter a positive integer: 16
16 is a square number [sqrt(16)=4]

Enter a positive integer: 213
-17...12 [sqrt(196)=14...sqrt(225)=15]
```
##### Class Math

Docs.Oracle.com::class Math

Your program can use the sqrt(n) and floor(n) static methods defined in the Math class.

Your program is not allowed to use the Math.pow(n) static method.

##### Typecasting

The typecast operator () is used to change the data type of a variable when used in an expression.

Example typecast usages.

The argument n to Math.sqrt(n) is defined to be type double. If n is type int, then use a typecast.

```   double y = Math.sqrt((int)n)
```

The return value of Math.floor(x) is defined to be type double. If the return value is to be assigned to a variable name n of type int, then use a typecast.

```   int n = (int)Math.floor(y)
```
