Assignment:

This assignment will consist of three methods in addition to the main method. Class name is: Roots

Method names are: roots
You may not substitute other names. You must use the names provided above.

Requirements

Main method

1. Shall prompt the user using a print or println to input a single integer value.

2. Shall use a Scanner object to input a single integer value.

3. Shall call the "roots" method with the single int value provided by the Scanner.
First method (roots)

4. Shall have only one formal int parameter.

5. Shall have a void return type.

6. The parameter shall determine how many times to execute the internal loop of the method. Within the loop the method:
6.1. Shall prompt and input two integer values.
6.2. Shall use a Scanner object to input two integer values when prompted.
6.3. Shall print your name on one line.
6.4. Shall call the second "roots" method from inside of the print statement of "6.3". 6.5. Shall pass the second "roots" method the two input integer values as parameters.
6.6. Shall print the result of the call to the second roots method on the next line after the
requirement in "6.3."
6.7. Note : Only two lines will be printed for each iteration of this loop (from this method).
Second method (roots)

7. Shall have two formal int parameters.

8. Shall have a double return type.

9. Shall cast the two int parameters as doubles and pass to the third "roots" method.

10. The return value from the third "roots" method shall be printed on a single line. (from this method)

11. Shall compute and return the square root of the sum of the squares of the two int parameters ( Calculations to be performed in floating point). Algebraically it would look like this, (a^2 + b^2)^1/2
12. Note: you will need to use the Math package to compute the square root
Third method (roots)

12. Shall have two formal double parameters.

13. Shall have a double return type.

14. Shall compute and print the first parameter times 3 on one line. Ex: (first * 3.0)

15. Shall compute and return the result of the following computation:
    15.1. First parameter times 100.0 with the result divided by 3 times the second parameter. Algebraically it looks like:

       15.1.1. (first * 100.0) /(second * 3) Output Example

Your output should look like the following example, but it will have different numeric values (based on your input) and of course your name, not mine. If you follow the requirements strictly, you get the same results:

Enter a single integer value =>
2
Please enter two integer values =>
3 4 9.0 25.0
